106-479: The Echo Show was unveiled on May 9, 2017, and released in the United States on June 28, 2017. It has received positive reviews, with critics noting its improved sound quality over the standard Echo speaker, its simplicity, and how the screen is used to supplement Alexa rather than act as a full-featured tablet . Critics have also noted that many third-party Alexa functions have not been updated to fully utilize

212-621: A Mac OS X -based tablet computer. The Modbook uses Apple's Inkwell for handwriting and gesture recognition, and uses digitization hardware from Wacom . To get Mac OS X to talk to the digitizer on the integrated tablet, the Modbook was supplied with a third-party driver. Following the launch of the Ultra-mobile PC , Intel began the Mobile Internet Device initiative, which took the same hardware and combined it with

318-455: A local area network (LAN). Tablets, like conventional PCs, use several different operating systems , though dual-booting is rare. Tablet operating systems come in two classes: Desktop OS-based tablets are currently thicker and heavier. They require more storage and more cooling and give less battery life. They can run processor-intensive graphical applications in addition to mobile apps , and have more ports . Mobile-based tablets are

424-529: A 5 MP camera. The Echo Show 5 was updated in 2023 with new processors, including the Amazon AZ2, and a larger speaker. The screen on Echo Show can be used to display visual output for Alexa assistant responses. The devices contain motion sensors to automatically wake its screen when someone enters a room; in this state, it can also display prompts regarding news headlines, suggested Alexa commands, and other information. Alexa can also be used to request

530-466: A 7-inch display while Vega's was 15 inches. Many more products followed in 2010. Several manufacturers waited for Android Honeycomb , specifically adapted for use with tablets, which debuted in February 2011. Apple is often credited for defining a new class of consumer device with the iPad , which shaped the commercial market for tablets in the following years, and was the most successful tablet at

636-446: A Debian-based Linux distribution custom-made for their Internet tablet line. The user interface and application framework layer, named Hildon , was an early instance of a software platform for generic computing in a tablet device intended for internet consumption. But Nokia did not commit to it as their only platform for their future mobile devices and the project competed against other in-house platforms and later replaced it with

742-556: A comparably-sized laptop, wireless local area and internet connectivity (usually with Wi-Fi standard and optional mobile broadband ), Bluetooth for connecting peripherals and communicating with local devices, ports for wired connections and charging, for example USB ports , Early devices had IR support and could work as a TV remote controller , docking station , keyboard and added connectivity, on-board flash memory , ports for removable storage, various cloud storage services for backup and syncing data across devices, local storage on

848-418: A database query to return information. The notable standalone runtimes are Node.js , Deno , and Bun . The following features are common to all conforming ECMAScript implementations unless explicitly specified otherwise. JavaScript supports much of the structured programming syntax from C (e.g., if statements, while loops, switch statements, do while loops, etc.). One partial exception

954-578: A desire in the flourishing web development scene to remove this limitation, so in 1995, Netscape decided to add a programming language to Navigator. They pursued two routes to achieve this: collaborating with Sun Microsystems to embed the Java language, while also hiring Brendan Eich to embed the Scheme language. The goal was a "language for the masses", "to help nonprogrammers create dynamic, interactive Web sites ". Netscape management soon decided that

1060-443: A full OS with an app store, but the sound quality alone justified its higher price over the original Echo. In a review of the second-generation model, Pocket-lint praised its improvements to audio quality (albeit being "bass-heavy"), screen size, Zigbee support, and "neater" design. The display was panned for being too reflective and having a near- 720p resolution. In addition, it was noted that optimization of third-party Skills for

1166-415: A hardware and software perspective, and delivered in a business-to-business transaction. For example, in hardware, a transportation company may find that the consumer-grade GPS module in an off-the-shelf tablet provides insufficient accuracy, so a tablet can be customized and embedded with a professional-grade antenna to provide a better GPS signal. Such tablets may also be ruggedized for field use. For

1272-488: A keyboard and stylus, which reflected the changing uses. As of early 2016, Android reigned over the market with 65%. Apple took the number 2 spot with 26%, and Windows took a distant third with the remaining 9%. In 2018, out of 4.4 billion computing devices Android accounted for 2 billion, iOS for 1 billion, and the remainder were PCs, in various forms (desktop, notebook, or tablet), running various operating systems (Windows, macOS, ChromeOS, Linux, etc.). Since

1378-479: A keyboard or mouse. This operation makes precise use of our eye–hand coordination . Touchscreens usually come in one of two forms: Since mid-2010s, most tablets use capacitive touchscreens with multi-touch , unlike earlier resistive touchscreen devices which users needed styluses to perform inputs. There are also electronic paper tablets such as Sony Digital Paper DPTS1 and reMarkable that use E ink for its display technology. Many tablets support

1484-486: A large product category used for personal, educational and workplace applications. Popular uses for a tablet PC include viewing presentations, video-conferencing, reading e-books, watching movies, sharing photos and more. As of 2021 there are 1.28 billion tablet users worldwide according to data provided by Statista , while Apple holds the largest manufacturer market share followed by Samsung and Lenovo . The tablet computer and its associated operating system began with

1590-570: A mobile operating system such as Android have incorporated modern functionally including internet browsing and multimedia capabilities; for example Huawei MatePad Paper is a tablet that uses e-ink instead of typical LCD or LED panel, hence focusing on the reading digital content while maintaining the internet and multimedia capabilities. Some E-reader such as PocketBook InkPad Color and ONYX BOOX NOVA 3 Color even came with colored e-ink panel and speaker which allowed for higher degree of multimedia consumption and video playback. The Kindle line from Amazon

1696-520: A more significant approach to tablets in 2002 as it attempted to define the Microsoft Tablet PC as a mobile computer for field work in business, though their devices failed, mainly due to pricing and usability decisions that limited them to their original purpose – such as the existing devices being too heavy to be held with one hand for extended periods, and having legacy applications created for desktop interfaces and not well adapted to

1802-467: A pair of two-inch speakers and is distinguished from other Echo products by containing a 7-inch touchscreen. As with other Echo devices, it can conduct voice calls, as well as video calls to other Echo Show users and through Skype with its 5-megapixel front-facing camera. The second-generation Echo Show (released in October 2018) is completely redesigned from the first generation. The new device replaces

1908-724: A software example, the same transportation company might remove certain software functions in the Android system, such as the internet browser, to reduce costs from needless cellular network data consumption of an employee, and add custom package management software. Other applications may call for a resistive touchscreen and other special hardware and software. A table ordering tablet is a touchscreen tablet computer designed for use in casual restaurants . Such devices allow users to order food and drinks, play games and pay their bill. Since 2013, restaurant chains including Chili's , Olive Garden and Red Robin have adopted them. As of 2014,

2014-452: A stand-alone JavaScript runtime system. As of 2018, Node had been used by millions of developers, and npm had the most modules of any package manager in the world. The ECMAScript draft specification is currently maintained openly on GitHub , and editions are produced via regular annual snapshots. Potential revisions to the language are vetted through a comprehensive proposal process. Now, instead of edition numbers, developers check

2120-429: A stylus and support handwriting recognition . Wacom and N-trig digital pens provide approximately 2500 DPI resolution for handwriting, exceeding the resolution of capacitive touch screens by more than a factor of 10. These pens also support pressure sensitivity, allowing for "variable-width stroke-based" characters, such as Chinese/Japanese/Korean writing, due to their built-in capability of "pressure sensing". Pressure

2226-675: A tabletized Linux configuration. Intel codeveloped the lightweight Moblin (mobile Linux) operating system following the successful launch of the Atom CPU series on netbooks. In 2010, Nokia and Intel combined the Maemo and Moblin projects to form MeeGo, a Linux-based operating system supports netbooks and tablets. The first tablet using MeeGo was the Neofonie WeTab launched September 2010 in Germany. The WeTab used an extended version of

In November 2013, Apple released the iPad Mini 2 , which remained at 7.9 inches and nearly matched the hardware of the iPad Air . Smartphones and tablets are similar devices, differentiated by the former typically having smaller screens and most tablets lacking cellular network capability. Since 2010, crossover touchscreen smartphones with screens larger than 5 inches have been released. That size

2438-886: A variety of other software systems, both for server-side website deployments and non-browser applications . Initial attempts at promoting server-side JavaScript usage were Netscape Enterprise Server and Microsoft 's Internet Information Services , but they were small niches. Server-side usage eventually started to grow in the late 2000s, with the creation of Node.js and other approaches . Electron , Cordova , React Native , and other application frameworks have been used to create many applications with behavior implemented in JavaScript. Other non-browser applications include Adobe Acrobat support for scripting PDF documents and GNOME Shell extensions written in JavaScript. JavaScript has been used in some embedded systems , usually by leveraging Node.js. A JavaScript engine

2544-520: A white paper in which he coined the term Ajax and described a set of technologies, of which JavaScript was the backbone, to create web applications where data can be loaded in the background, avoiding the need for full page reloads. This sparked a renaissance period of JavaScript, spearheaded by open-source libraries and the communities that formed around them. Many new libraries were created, including jQuery , Prototype , Dojo Toolkit , and MooTools . Google debuted its Chrome browser in 2008, with

2650-484: Is multi-paradigm , supporting event-driven , functional , and imperative programming styles . It has application programming interfaces (APIs) for working with text, dates, regular expressions , standard data structures , and the Document Object Model (DOM). The ECMAScript standard does not include any input/output (I/O), such as networking , storage , or graphics facilities. In practice,

2756-530: Is scoping : originally JavaScript only had function scoping with var ; block scoping was added in ECMAScript 2015 with the keywords let and const . Like C, JavaScript makes a distinction between expressions and statements . One syntactic difference from C is automatic semicolon insertion , which allow semicolons (which terminate statements) to be omitted. JavaScript is weakly typed , which means certain types are implicitly cast depending on

2862-455: Is a software component that executes JavaScript code . The first JavaScript engines were mere interpreters , but all relevant modern engines use just-in-time compilation for improved performance. JavaScript engines are typically developed by web browser vendors, and every major browser has one. In a browser, the JavaScript engine runs in concert with the rendering engine via the Document Object Model and Web IDL bindings. However,

2968-628: Is also a gaming tablet that runs on its own system software , features detachable Joy-Con controllers with motion controls and three gaming modes: table-top mode using its kickstand, traditional docked/TV mode and handheld mode. While not entirely an actual tablet form factor due to their sizes, some other handheld console including the smaller version of Nintendo Switch, the Nintendo Switch Lite , and PlayStation Vita are treated as an gaming tablet or tablet replacement by community and reviewer/publisher due to their capabilities on browsing

3074-401: Is also used in digital art applications such as Autodesk Sketchbook . Apps exist on both iOS and Android platforms for handwriting recognition and in 2015 Google introduced its own handwriting input with support for 82 languages. After 2007, with access to capacitive screens and the success of the iPhone, other features became common, such as multi-touch features (in which the user can touch

3180-487: Is by far the most-used. Other notable ones include Angular , Bootstrap , Lodash , Modernizr , React , Underscore , and Vue . Multiple options can be used in conjunction, such as jQuery and Bootstrap. However, the term "Vanilla JS" was coined for websites not using any libraries or frameworks at all, instead relying entirely on standard JavaScript functionality. The use of JavaScript has expanded beyond its web browser roots. JavaScript engines are now embedded in

3286-491: Is directly related to Java. At the time, the dot-com boom had begun and Java was a popular new language, so Eich considered the JavaScript name a marketing ploy by Netscape. Microsoft debuted Internet Explorer in 1995, leading to a browser war with Netscape. On the JavaScript front, Microsoft created its own interpreter called JScript . Microsoft first released JScript in 1996, alongside initial support for CSS and extensions to HTML . Each of these implementations

3392-411: Is generally considered larger than a traditional smartphone, creating the hybrid category of the phablet by Forbes and other publications. "Phablet" is a portmanteau of "phone" and "tablet". At the time of the introduction of the first phablets, they had screens of 5.3 to 5.5 inches, but as of 2017 screen sizes up to 5.5 inches are considered typical. Examples of phablets from 2017 and onward are

3498-601: Is the dominant client-side scripting language of the Web, with 99% of all websites using it for this purpose. Scripts are embedded in or included from HTML documents and interact with the DOM . All major web browsers have a built-in JavaScript engine that executes the code on the user's device. Over 80% of websites use a third-party JavaScript library or web framework as part of their client-side scripting. jQuery

3604-521: Is touch input on a touchscreen display. This allows the user to navigate easily and type with a virtual keyboard on the screen or press other icons on the screen to open apps or files. The first tablet to do this was the GRiDPad by GRiD Systems Corporation ; the tablet featured both a stylus , a pen-like tool to aid with precision in a touchscreen device as well as an on-screen keyboard. The system must respond to on-screen touches rather than clicks of

3710-460: The Apple Newton personal digital assistant in 1993. It used Apple's own new Newton OS , initially running on hardware manufactured by Motorola and incorporating an ARM CPU, that Apple had specifically co-developed with Acorn Computers . The operating system and platform design were later licensed to Sharp and Digital Ocean , who went on to manufacture their own variants. Pen computing

3816-567: The JooJoo . Intel announced plans to enter the tablet market with its Atom in 2010. In October 2013, Intel's foundry operation announced plans to build FPGA-based quad cores for ARM and x86 processors. ARM has been the CPU architecture of choice for manufacturers of smartphones (95% ARM), PDAs, digital cameras (80% ARM), set-top boxes , DSL routers, smart televisions (70% ARM), storage devices and tablet computers (95% ARM). This dominance began with

3922-641: The Mozilla Foundation announced a prototype tablet model with Foxconn which ran on Firefox OS . Firefox OS was discontinued in 2016. The Canonical hinted that Ubuntu would be available on tablets by 2014. In February 2016, there was a commercial release of the BQ Aquaris Ubuntu tablet using the Ubuntu Touch operating system. Canonical terminated support for the project due to lack of market interest on April 5, 2017 and it

4028-761: The Samsung Galaxy Note series (newer models of 5.7 inches), the LG V10 / V20 (5.7 inches), the Sony Xperia XA Ultra (6 inches), the Huawei Mate 9 (5.9 inches), and the Huawei Honor (MediaPad) X2 (7 inches). A 2-in-1 PC is a hybrid or combination of a tablet and laptop computer that has features of both. Distinct from tablets, 2-in-1 PCs all have physical keyboards , but they are either concealable by folding them back and under

4134-1164: The Samsung Galaxy Tab Pro 12.2 at 12.2 inches (31 cm), the Toshiba Excite at 13.3 inches (33 cm) and the Dell XPS 18 at 18.4 inches (47 cm). As of March 2013, the thinnest tablet on the market was the Sony Xperia Tablet Z at only 0.27 inches (6.9 mm) thick. On September 9, 2015, Apple released the iPad Pro with a 12.9 inches (33 cm) screen size, larger than the regular iPad . Mini tablets are smaller and weigh less than slates, with typical screen sizes between 7–8 inches (18–20 cm). The first commercially successful mini tablets were introduced by Amazon.com ( Kindle Fire ), Barnes & Noble ( Nook Tablet ), and Samsung ( Galaxy Tab ) in 2011; and by Google ( Nexus 7 ) in 2012. They operate identically to ordinary tablets but have lower specifications compared to them. On September 14, 2012, Amazon, Inc. released an upgraded version of

4240-545: The Series 60 . Nokia used the term internet tablet to refer to a portable information appliance that focused on Internet use and media consumption, in the range between a personal digital assistant (PDA) and an Ultra-Mobile PC (UMPC). They made two mobile phones, the N900 that runs Maemo, and N9 that run Meego. Before the release of iPad, Axiotron introduced an aftermarket, heavily modified Apple MacBook called Modbook ,

4346-511: The V8 JavaScript engine that was faster than its competition. The key innovation was just-in-time compilation (JIT), so other browser vendors needed to overhaul their engines for JIT. In July 2008, these disparate parties came together for a conference in Oslo . This led to the eventual agreement in early 2009 to combine all relevant work and drive the language forward. The result was

4452-545: The client side for webpage behavior. Web browsers have a dedicated JavaScript engine that executes the client code . These engines are also utilized in some servers and a variety of apps . The most popular runtime system for non-browser usage is Node.js . JavaScript is a high-level , often just-in-time compiled language that conforms to the ECMAScript standard. It has dynamic typing , prototype-based object-orientation , and first-class functions . It

4558-553: The mouse , touchpad , and keyboard of larger computers. Portable computers can be classified according to the presence and appearance of physical keyboards. Two species of tablet, the slate and booklet , do not have physical keyboards and usually accept text and other input by use of a virtual keyboard shown on their touchscreen displays. To compensate for their lack of a physical keyboard, most tablets can connect to independent physical keyboards by Bluetooth or USB ; 2-in-1 PCs have keyboards, distinct from tablets. The form of

4664-473: The touchscreen and all other features of a typical tablet computer. Most of these tablets are targeted to run native OS games and emulator games. Nvidia 's Shield Tablet , with an 8-inch (200 mm) display, and running Android , is an example. It runs Android games purchased from Google Play store. PC games can also be streamed to the tablet from computers with some higher end models of Nvidia-powered video cards . The Nintendo Switch hybrid console

4770-479: The 1980s, with various input/output types tried out. Tablet computers appeared in a number of works of science fiction in the second half of the 20th century; all helped to promote and disseminate the concept to a wider audience. Examples include: Further, real-life projects either proposed or created tablet computers, such as: Following earlier tablet computer products such as the Pencept PenPad, and

4876-467: The Americas. Android tablets were more popular in most of Asia (China and Russia an exception), Africa and Eastern Europe. In 2015 tablet sales did not increase. Apple remained the largest seller but its market share declined below 25%. Samsung vice president Gary Riding said early in 2016 that tablets were only doing well among those using them for work. Newer models were more expensive and designed for

4982-946: The CIC Handwriter, in September 1989, GRiD Systems released the first commercially successful tablet computer, the GRiDPad . All three products were based on extended versions of the MS-DOS operating system. In 1992, IBM announced (in April) and shipped to developers (in October) the ThinkPad 700T (2521) , which ran the GO Corporation 's PenPoint OS . Also based on PenPoint was AT&T 's EO Personal Communicator from 1993, which ran on AT&T's own hardware, including their own AT&T Hobbit CPU. Apple Computer launched

5088-570: The ECMAScript 5 standard, released in December 2009. Ambitious work on the language continued for several years, culminating in an extensive collection of additions and refinements being formalized with the publication of ECMAScript 6 in 2015. The creation of Node.js in 2009 by Ryan Dahl sparked a significant increase in the usage of JavaScript outside of web browsers. Node combines the V8 engine, an event loop , and I/O APIs , thereby providing

5194-466: The Echo Show to previous "internet appliances" such as the 3Com Audrey and Chumby , but acknowledged that neither of them was equipped with a voice-activated virtual assistant , and both were built with too much functionality. In comparison, Amazon was praised for having intentionally limited the amount of touchscreen-oriented functionality on the Echo Show, so that the device would not be complex. It

5300-471: The Echo Show was still inconsistent. Tablet computer A tablet computer , commonly shortened to tablet , is a mobile device , typically with a mobile operating system and touchscreen display processing circuitry , and a rechargeable battery in a single, thin and flat package. Tablets, being computers, have similar capabilities, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones ,

5406-696: The Kindle Fire, the Kindle Fire HD , with higher screen resolution and more features compared to its predecessor, yet remaining only 7 inches. In October 2012, Apple released the iPad Mini with a 7.9-inch screen size, about 2 inches smaller than the regular iPad , but less powerful than the then current iPad 3 . On July 24, 2013, Google released an upgraded version of the Nexus 7 , with FHD display, dual cameras, stereo speakers, more color accuracy, performance improvement, built-in wireless charging , and

5512-662: The MeeGo operating system called WeTab OS. WeTab OS adds runtimes for Android and Adobe AIR and provides a proprietary user interface optimized for the WeTab device. On September 27, 2011, the Linux Foundation announced that MeeGo would be replaced in 2012 by Tizen . Android was the first of the 2000s-era dominating platforms for tablet computers to reach the market. In 2008, the first plans for Android-based tablets appeared. The first products were released in 2009. Among them

5618-493: The U.S. and China. Android is a Linux -based operating system that Google offers as open source under the Apache license . It is designed primarily for mobile devices such as smartphones and tablet computers. Android supports low-cost ARM systems and others. The first tablets running Android were released in 2009. Vendors such as Motorola and Lenovo delayed deployment of their tablets until after 2011, when Android

5724-414: The United States. The trademark was originally issued to Sun Microsystems on 6 May 1997, and was transferred to Oracle when they acquired Sun in 2009. A letter was circulated in September 2024, spearheaded by Ryan Dahl , calling on Oracle to free the JavaScript trademark . Brendan Eich the original creator of JavaScript, was among the over 14,000 signatories who supported the initiative. JavaScript

5830-426: The ability to import scripts. JavaScript is a single- threaded language. The runtime processes messages from a queue one at a time, and it calls a function associated with each new message, creating a call stack frame with the function's arguments and local variables . The call stack shrinks and grows based on the function's needs. When the call stack is empty upon function completion, JavaScript proceeds to

5936-557: The architecture, shipping their own ARM-based tablet computer, branded the Microsoft Surface , as well as an x86-64 Intel Core i5 variant branded as Microsoft Surface Pro. Intel tablet chip sales were 1 million units in 2012, and 12 million units in 2013. Intel chairman Andy Bryant has stated that its 2014 goal is to quadruple its tablet chip sales to 40 million units by the end of that year, as an investment for 2015. A key component among tablet computers

6042-450: The best option was for Eich to devise a new language, with syntax similar to Java and less like Scheme or other extant scripting languages . Although the new language and its interpreter implementation were called LiveScript when first shipped as part of a Navigator beta in September 1995, the name was changed to JavaScript for the official release in December. The choice of the JavaScript name has caused confusion, implying that it

6148-646: The black plastic with a mesh casing while keeping the same device shape. The speakers were moved to the side and back of the device to allow a 3-inch larger display. Amazon claims that the new version will have better sound quality. It also integrates a Zigbee hub, similar to the Echo Plus. The Echo Show 5 is a variation with a 5.5-inch display. The Echo Show 8 is a variation with an 8" display, announced in September 2019 for shipment in November 2019. The third-generation Echo Show (released in February 2021) changed

6254-595: The company was dissolved in 2003. Sony released its Airboard tablet in Japan in late 2000 with full wireless Internet capabilities. In the late 1990s, Microsoft launched the Handheld PC platform using their Windows CE operating system; while most devices were not tablets, a few touch enabled tablets were released on the platform such as the Fujitsu PenCentra 130 or Siemens 's SIMpad . Microsoft took

6360-521: The development of pen computing . Electrical devices with data input and output on a flat information display existed as early as 1888 with the telautograph , which used a sheet of paper as display and a pen attached to electromechanical actuators . Throughout the 20th century devices with these characteristics have been imagined and created whether as blueprints , prototypes , or commercial products . In addition to many academic and research systems, several companies released commercial products in

6466-430: The early 2020s, various companies such as Samsung are beginning to introduce foldable technology into their tablets. Tablets can be loosely grouped into several categories by physical size, kind of operating system installed, input and output technology, and uses. The size of a slate varies, but slates begin at 6 inches (approximately 15 cm). Some models in the larger than 10-inch (25 cm) category include

6572-491: The effort to fully standardize the language was undermined by Microsoft gaining an increasingly dominant position in the browser market. By the early 2000s, Internet Explorer 's market share reached 95%. This meant that JScript became the de facto standard for client-side scripting on the Web. Microsoft initially participated in the standards process and implemented some proposals in its JScript language, but eventually it stopped collaborating on ECMA work. Thus ECMAScript 4

6678-640: The form factor to have a cylindrical speaker base with a screen which can rotate around it, with voice direction detection and computer vision human detection. The Echo Show 5 was updated in June 2021 with an improved 2 MP camera. The Echo Show 8 was updated in June 2021 with an improved 13 MP camera. The Echo Show 15 is a 15.6-inch, 1080p Full HD device designed to be wall-mounted (a departure from previous tabletop forms). Announced on September 28, 2021, in Amazon's 'Devices and Services Event' it also includes

6784-598: The internet and multimedia capabilities. Booklets are dual-touchscreen tablet computers with a clamshell design that can fold like a laptop. Examples include the Microsoft Courier , which was discontinued in 2010, the Sony Tablet P (considered a flop), and the Toshiba Libretto W100. Customized business tablets are built specifically for a business customer's particular needs from

6890-471: The larger Google Play system, thereby fragmenting the Android market. In 2022 Google began to re-emphasize in-house Android tablet development — at this point, a multi-year commitment. JavaScript This is an accepted version of this page JavaScript ( / ˈ dʒ ɑː v ə s k r ɪ p t / ), often abbreviated as JS , is a programming language and core technology of the Web , alongside HTML and CSS . 99% of websites use JavaScript on

6996-507: The launch of the second-generation Echo Show, Amazon claimed that the issue was now fixed. YouTube searches are now performed using the Silk or Firefox web browsers on the device. In November 2019, a security research team in the Pwn2Own hacking contest hacked into an Amazon Echo Show 5. They did so by hacking into the "patch gap" that meshed older software patched onto other platforms, as

7102-414: The next message in the queue. This is called the event loop , described as "run to completion" because each message is fully processed before the next message is considered. However, the language's concurrency model describes the event loop as non-blocking : program I/O is performed using events and callback functions . This means, for example, that JavaScript can process a mouse click while waiting for

7208-506: The old status bar at the bottom of your old browser ." In November 1996, Netscape submitted JavaScript to Ecma International , as the starting point for a standard specification that all browser vendors could conform to. This led to the official release of the first ECMAScript language specification in June 1997. The standards process continued for a few years, with the release of ECMAScript 2 in June 1998 and ECMAScript 3 in December 1999. Work on ECMAScript 4 began in 2000. However,

7314-481: The only differences being that tablets are relatively larger than smartphones, with screens 7 inches (18 cm) or larger, measured diagonally, and may not support access to a cellular network . Unlike laptops (which have traditionally run off operating systems usually designed for desktops), tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by gestures executed by finger or digital pen (stylus), instead of

7420-409: The operation used. Values are cast to strings like the following: Values are cast to numbers by casting to strings and then casting the strings to numbers. These processes can be modified by defining toString and valueOf functions on the prototype for string and number casting respectively. JavaScript has received criticism for the way it implements these conversions as the complexity of

7526-505: The option of connecting a conventional Keyboard and mouse. Intel announced a StrongARM processor-based touchscreen tablet computer in 1999, under the name WebPAD. It was later re-branded as the "Intel Web Tablet". In 2000, Norwegian company Screen Media AS and the German company Dosch & Amand Gmbh released the "FreePad". It was based on Linux and used the Opera browser . Internet access

7632-462: The playback of videos on its screen, such as Amazon Video content. The "Drop In" feature allows users to, between designated contacts, automatically begin a call unannounced. The Echo Show initially supported YouTube videos; on September 26, 2017, it was revealed that Google (who manufactures Google Home , a direct competitor to the Amazon Echo line) had blocked the device's access to

7738-454: The rapid growth of the early World Wide Web . The lead developers of Mosaic then founded the Netscape corporation, which released a more polished browser, Netscape Navigator , in 1994. This quickly became the most-used. During these formative years of the Web, web pages could only be static, lacking the capability for dynamic behavior after the page was loaded in the browser. There was

7844-542: The release of the mobile-focused and comparatively power-efficient 32-bit ARM610 processor originally designed for the Apple Newton in 1993 and ARM3-using Acorn A4 laptop in 1992. The chip was adopted by Psion, Palm and Nokia for PDAs and later smartphones, camera phones, cameras, etc. ARM's licensing model supported this success by allowing device manufacturers to license, alter and fabricate custom SoC derivatives tailored to their own products. This has helped manufacturers extend battery life and shrink component count along with

7950-606: The reverse, and run only mobile apps. They can use battery life conservatively because the processor is significantly smaller. This allows the battery to last much longer than the common laptop. In Q1 2018, Android tablets had 62% of the market, Apple's iOS had 23.4% of the market and Windows 10 had 14.6% of the market. In late 2021, iOS has 55% use worldwide (varies by continent, e.g. below 50% in South America and Africa) and Android 45% use. Still, Android tablets have more use than iOS in virtually all countries, except for e.g.

8056-437: The rules can be mistaken for inconsistency. For example, when adding a number to a string, the number will be cast to a string before performing concatenation, but when subtracting a number from a string, the string is cast to a number before performing subtraction. Often also mentioned is {} + [] resulting in 0 (number). This is misleading: the {} is interpreted as an empty code block instead of an empty object, and

8162-590: The screen in multiple places to trigger actions and other natural user interface features, as well as flash memory solid state storage and "instant on" warm-booting ; external USB and Bluetooth keyboards defined tablets. Most tablets released since mid-2010 use a version of an ARM processor for longer battery life. The ARM Cortex family is powerful enough for tasks such as internet browsing , light creative and production work and mobile games . Other features are: High-definition, anti-glare display , touchscreen, lower weight and longer battery life than

8268-459: The screen). However, it was felt that the "unfinished" Alexa still hampered the experience (noting an error where it played the film Creed when asked to play music by the band Creed ), and that some Skills had not been updated to fully support the screen, but that "if nothing else, it is fun to poke around and explore what else Alexa can do." In conclusion, it was argued that at its price point, it could have featured higher-quality speakers and

8374-566: The screen. The Echo Show was unveiled on May 9, 2017, and released in the United States on June 28, 2017. A second generation of the Echo Show was unveiled at an Alexa-themed product event by Amazon on September 20, 2018, for release the following month. This device has a 10-inch touchscreen, improved speakers, and mesh casing. An Echo Show with a smaller, 5.5-inch screen was announced in May 2019 and launched in 12 countries in June 2019. The first-generation Echo Show (released in June 2017) contains

8480-491: The service, citing violations of its terms of service and ongoing negotiations. While Amazon later worked around the restriction by using the web version, Google announced that it would block YouTube from the Echo Show, as well as the Fire TV platform, citing Amazon's ongoing restrictions against the sale of products which compete with its own video ecosystem, and refusal to support its own video platform on Google devices . At

8586-405: The size of devices. The multiple licensees ensured that multiple fabricators could supply near-identical products, while encouraging price competition. This forced unit prices down to a fraction of their x86 equivalents. The architecture has historically had limited support from Microsoft, with only Windows CE available, but with the 2012 release of Windows 8, Microsoft announced added support for

8692-514: The slate format. Nokia had plans for an Internet tablet since before 2000. An early model was test manufactured in 2001, the Nokia M510, which was running on EPOC and featuring an Opera browser, speakers and a 10-inch 800×600 screen, but it was not released because of fears that the market was not ready for it. Nokia entered the tablet space in May 2005 with the Nokia 770 running Maemo ,

8798-414: The smart screen used an old version of Chromium . The security team exploited the code using "an integer overflow JavaScript bug to hijack the device while it was connected to a malicious WiFi network ." The bug allowed them to take "full control" of the device. The team shared the findings with Amazon, which said it was investigating the hack, and would take "appropriate steps." The Verge compared

8904-436: The status of upcoming features individually. The current JavaScript ecosystem has many libraries and frameworks , established programming practices, and substantial usage of JavaScript outside of web browsers. Plus, with the rise of single-page applications and other JavaScript-heavy websites, several transpilers have been created to aid the development process. "JavaScript" is a trademark of Oracle Corporation in

9010-468: The tablet market, ARM Ltd. 's ARM architecture and Intel's and AMD's x86 . Intel's x86, including x86-64 has powered the "IBM compatible" PC since 1981 and Apple's Macintosh computers since 2006. The CPUs have been incorporated into tablet PCs over the years and generally offer greater performance along with the ability to run full versions of Microsoft Windows , along with Windows desktop and enterprise applications. Non-Windows based x86 tablets include

9116-402: The tablet was conceptualized in the middle of the 20th century ( Stanley Kubrick depicted fictional tablets in the 1968 science fiction film 2001: A Space Odyssey ) and prototyped and developed in the last two decades of that century. In 2010, Apple released the iPad , the first mass-market tablet to achieve widespread popularity. Thereafter, tablets rapidly rose in ubiquity and soon became

9222-477: The time of its release. iPads and competing devices were tested by the U.S. military in 2011 and cleared for secure use in 2013. Its debut in 2010 pushed tablets into the mainstream. Samsung 's Galaxy Tab and others followed, continuing the trends towards the features listed above. In March 2012, PC Magazine reported that 31% of U.S. Internet users owned a tablet, used mainly for viewing published content such as video and news. The top-selling line of devices

9328-936: The touchscreen ("2-in-1 convertible") or detachable ("2-in-1 detachable"). 2-in-1s typically also can display a virtual keyboard on their touchscreens when their physical keyboards are concealed or detached. Some 2-in-1s have processors and operating systems like those of laptops, such as Windows 10 , while having the flexibility of operation as a tablet. Further, 2-in-1s may have typical laptop I/O ports, such as USB 3 and DisplayPort , and may connect to traditional PC peripheral devices and external displays. Simple tablets are mainly used as media consumption devices, while 2-in-1s have capacity for both media consumption and content creation , and thus 2-in-1s are often called laptop or desktop replacement computers . There are two species of 2-in-1s: Some tablets are modified by adding physical gamepad buttons such as D-pad and thumb sticks for better gaming experience combined with

9434-424: The two most popular brands were Ziosk and Presto . The devices have been criticized by servers who claim that some restaurants determine their hours based on customer feedback in areas unrelated to service. Any device that can display text on a screen may act as an E-reader . While traditionally E-readers are designed primarily for the purpose of reading digital e-books and periodicals, modern E-readers that use

9540-506: The use of JavaScript engines is not limited to browsers; for example, the V8 engine is a core component of the Node.js runtime system . A JavaScript engine must be embedded within a runtime system (such as a web browser or a standalone system) to enable scripts to interact with the broader environment. The runtime system includes the necessary APIs for input/output operations, such as networking , storage , and graphics , and provides

9646-402: The web browser or other runtime system provides JavaScript APIs for I/O. Although Java and JavaScript are similar in name, syntax , and respective standard libraries , the two languages are distinct and differ greatly in design. The first popular web browser with a graphical user interface , Mosaic , was released in 1993. Accessible to non-technical people, it played a prominent role in

9752-587: Was Apple's iPad with 100 million sold between its release in April 2010 and mid-October 2012, but iPad market share (number of units) dropped to 36% in 2013 with Android tablets climbing to 62%. Android tablet sales volume was 121 million devices, plus 52 million, between 2012 and 2013 respectively. Individual brands of Android operating system devices or compatibles follow iPad with Amazon's Kindle Fire with 7 million, and Barnes & Noble's Nook with 5 million. The BlackBerry PlayBook

9858-596: Was announced in September 2010 that ran the BlackBerry Tablet OS . The BlackBerry PlayBook was officially released to US and Canadian consumers on April 19, 2011. Hewlett-Packard announced that the TouchPad , running WebOS 3.0 on a 1.2 GHz Qualcomm Snapdragon CPU, would be released in June 2011. On August 18, 2011, HP announced the discontinuation of the TouchPad, due to sluggish sales. In 2013,

9964-581: Was based on an ECMAScript 4 draft. The goal became standardizing ActionScript 3 as the new ECMAScript 4. To this end, Adobe Systems released the Tamarin implementation as an open source project. However, Tamarin and ActionScript 3 were too different from established client-side scripting, and without cooperation from Microsoft , ECMAScript 4 never reached fruition. Meanwhile, very important developments were occurring in open-source communities not affiliated with ECMA work. In 2005, Jesse James Garrett released

10070-473: Was felt that "from nearly any other company, adding a screen would have resulted in feature-itis of the worst kind. By holding back, the Echo Show feels like it does more. Its strength is in its simplicity." Pocket-lint felt that the white model had an "air of modern", but the black model looked "kind of dated, oddly boxy, and just downright blah to us". The updated mesh fabric covering on the second-generation product addressed these complaints. Its sound quality

10176-480: Was highly hyped by the media during the early 1990s. Microsoft , the dominant PC software vendor, released Windows for Pen Computing in 1992 to compete against PenPoint OS. The company launched the WinPad project, working together with OEMs such as Compaq , to create a small device with a Windows -like operating system and handwriting recognition. However, the project was abandoned two years later; instead Windows CE

10282-641: Was mothballed. During the period of Internet Explorer dominance in the early 2000s, client-side scripting was stagnant. This started to change in 2004, when the successor of Netscape, Mozilla , released the Firefox browser. Firefox was well received by many, taking significant market share from Internet Explorer. In 2005, Mozilla joined ECMA International, and work started on the ECMAScript for XML (E4X) standard. This led to Mozilla working jointly with Macromedia (later acquired by Adobe Systems ), who were implementing E4X in their ActionScript 3 language, which

10388-483: Was noted that few third-party Alexa Skills actually took advantage of the screen, and there were limited options for video services that integrated with Alexa . The sound quality of the Echo Show was perceived as being superior to the standard Echo , but lower than other dedicated speakers at the same price point. The camera was also panned for being angled upwards (thus making it harder for shorter people to use), and for not handling backlighting well. In conclusion, it

10494-662: Was noticeably different from their counterparts in Netscape Navigator . These differences made it difficult for developers to make their websites work well in both browsers, leading to widespread use of "best viewed in Netscape" and "best viewed in Internet Explorer" logos for several years. Brendan Eich later said of this period: "It's still kind of a sidekick language. It's considered slow or annoying. People do pop-ups or those scrolling messages in

10600-473: Was originally limited to E-reading capabilities; however, an update to their Kindle firmware added the ability to browse the Internet and play audio, allowing Kindles to be alternatives to a traditional tablet, in some cases, with a more readable e-ink panel and greater battery life, and providing the user with access to wider multimedia capabilities compared to the older model. Two major architectures dominate

10706-443: Was praised for being able to "fill your entire room and then some", and the ability to look up and view YouTube videos was "not the fastest experience", but "quick enough and has yet to glitch out on us." The "Drop In" feature was praised as being potentially useful for checking on "elderly loved ones". The device was also praised for integrating with smart home products (such as home security cameras, which can display their feeds on

10812-572: Was provided by DECT DMAP, only available in Europe and provided up to 10 Mbit/s. The device had 16 MB storage, 32 MB of RAM and x86 compatible 166 MHz "Geode"-Microcontroller by National Semiconductor . The screen was 10.4" or 12.1" and was touch sensitive. It had slots for SIM cards to enable support of television set-up box. FreePad were sold in Norway and the Middle East; but

10918-536: Was released in the form of " Handheld PCs " in 1996. That year, Palm, Inc. released the first of the Palm OS based PalmPilot touch and stylus based PDA, the touch based devices initially incorporating a Motorola Dragonball (68000) CPU. Also in 1996 Fujitsu released the Stylistic 1000 tablet format PC, running Microsoft Windows 95 , on a 100 MHz AMD486 DX4 CPU, with 8 MB RAM offering stylus input, with

11024-506: Was reworked to include more tablet features. Android 3.0 (Honeycomb) , released in 2011 and later versions support larger screen sizes, mainly tablets, and have access to the Google Play service. Android includes operating system, middleware and key applications. Other vendors sell customized Android tablets, such as Kindle Fire and Nook , which are used to consume mobile content and provide their own app store, rather than using

11130-565: Was the Archos 5, a pocket-sized model with a 5-inch touchscreen , that was first released with a proprietary operating system and later (in 2009) released with Android 1.4. The Camangi WebStation was released in Q2 2009. The first LTE Android tablet appeared late 2009 and was made by ICD for Verizon . This unit was called the Ultra, but a version called Vega was released around the same time. Ultra had

11236-546: Was then adopted by the UBports as a community project. As of February 2014, 83% of mobile app developers were targeting tablets, but 93% of developers were targeting smartphones. By 2014, around 23% of B2B companies were said to have deployed tablets for sales-related activities, according to a survey report by Corporate Visions. The iPad held majority use in North America, Western Europe, Japan, Australia, and most of
