Hi

ECMAScript is a standard script language, developed with the cooperation of Netscape and Microsoft and mainly derived from Netscape's JavaScript, the widely-used scripting language that is used in Web pages to affect how they look or behave for the user. Microsoft states that its latest version of JScript is the first implementation of the ECMAScript standard. The official standard, ECMA-262, was developed under the auspices of the European Computer Manufacturers Association (ECMA). Having the ECMAScript standard will help ensure more consistency between Netscape, Microsoft, and any other Web script implementations.

ECMAScript is object-oriented and conceived as a core language to which can be added the objects of any specific domain or context such as the idea of a "document." (for example, the World Wide Web Consortium's Document Object Model). ECMAScript together with the Document Object Model corresponds closely to the current implementations of JavaScript and JScript. Although likely to be used mainly as a standard script language for the World Wide Web, ECMAScript could also be used for any scripted application.

Thanks
