JavaScript Language Reference

JavaScript is a scripting language that can be embedded in web pages and other applications.

This documentation describes the Microsoft implementation of JavaScript, which is compliant with the ECMAScript Language Specification 5th Edition. It also provides additional features that are not included in the ECMA Standards.

You can use JavaScript code in browser applications together with HTML, CSS and the Document Object Model (DOM), which represents HTML and browser objects.

You can also use JavaScript code in Windows Store apps. Windows Store apps run on Windows 8 and Windows 8.1, and they can be developed in Visual Studio 2012 and Visual Studio 2013.

The JavaScript editor in Visual Studio provides IntelliSense support. For more information, see JavaScript IntelliSense.
