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.
