JScript 10.0 is a separate dialect, also known as JScript .NET , which adds several new features from the abandoned fourth edition of the ECMAScript standard. It must be compiled for .NET Framework version 2 or version 4, but static type annotations are optional. JScript has been criticized for being insecure and having multiple security bugs "exploited by nation-state actors", leading Microsoft to add an option to disable it. As explained by Douglas Crockford in his talk titled The JavaScript Programming Language on YUI Theater, [Microsoft] did not want to deal with Sun Microsystems about
2352-533: Is a Microsoft .NET implementation of JScript. It is a CLI language and thus inherits very powerful features, but lacks many features of the original JScript language, making it inappropriate for many scripting scenarios.
