ARCHIVE / What is ECMAScript?

ECMAScript is an attempt at the industry-wide standardization of JavaScript and JScript.  As JavaScript was developed by Netscape and is currently continuing to be developed by the Mozilla Project, Microsoft came out with JScript in order to run JavaScript programs on its Internet Explorer browser while offering additional functionality that, if used, would cause pages using JScript not to run in other browsers.  This divergence of functionality led to severe problems for web site developers who often needed to make different versions of a web page in order for it to run properly on the increasingly differing web browsers.  Though the development of ECMAScript has effectively reduced the divergence by providing a referencing standard, it has not been able to remove the divergence completely.
