JavaScript

JavaScript is an object-based scripting programming language based on the concept of prototypes. The language is best known for its use in websites, but is also used to enable scripting access to objects embedded in other applications. It was originally developed by Brendan Eich of Netscape Communications Corporation under the name Mocha, then LiveScript, and finally renamed to JavaScript. Like Java, JavaScript has a C-like syntax, but it has far more in common with the Self programming language than with Java.

As of 2005, the latest version of the language is JavaScript 1.5, which corresponds to ECMA-262 Edition 3. ECMAScript, in simple terms, is a standardized version of JavaScript. Mozilla versions since 1.8 Beta 1 also have partial support of E4X, which is a language extension dealing with XML, defined in the ECMA-357 standard.
