JavaScript is a dialect of the standardized ECMAScript programming language, primarily used for scripting web-pages. Use this tag for questions regarding ECMAScript and its dialects/ implementations: JavaScript, JScript, etc., excluding ActionScript.

ECMAScript, JavaScript & JScript

ECMAScript was developed as a standardization of Netscape's JavaScript and Microsoft's JScript. The canonical reference is The ECMA-262 Language Specification. While JavaScript and JScript aim to be compatible with ECMAScript, they also provide additional features not described in the ECMA specifications. Other implementations of ECMAScript also exist.

The Basics

The Mozilla Developer Center offers good documentation on JavaScript.

JavaScript is most often used in the browser - see The Document Object Model.
