JAVA

       JavaScript, not to be confused with Java, was created in 10 days in May 1995 by Brendan Eich, then working at Netscape and now of Mozilla. JavaScript was not always known as JavaScript: the original name was Mocha, a name chosen by Marc Andreessen, founder of Netscape. In September of 1995 the name was changed to LiveScript, then in December of the same year, upon receiving a trademark license from Sun, the name JavaScript was adopted. This was somewhat of a marketing move at the time, with Java being very popular around then.
In 1996 - 1997 JavaScript was taken to ECMA to carve out a standard specification, which other browser vendors could then implement based on the work done at Netscape. The work done over this period of time eventually led to the official release of ECMA-262 Ed.1: ECMAScript is the name of the official standard, with JavaScript being the most well known of the implementations. ActionScript 3 is another well-known implementation of ECMAScript, with extensions (see below).
The standards process continued in cycles, with releases of ECMAScript 2 in 1998 and ECMAScript 3 in 1999, which is the baseline for modern day JavaScript. The "JS2" or "original ES4" work led by Waldemar Horwat (then of Netscape, now at Google) started in 2000 and at first, Microsoft seemed to participate and even implemented some of the proposals in their JScript.net language.
