It is used to make webpages interactive and provide online programs, including video games.
The majority of websites employ it, and all modern web browsers support it without the need for plug-ins by means of a built-in Java Script engine.
The internal codename for the company's browser was Mozilla, which stood for "Mosaic killer", as the company's goal was to displace NCSA Mosaic as the world's number one web browser.
These differences made it difficult for designers and programmers to make a single website work well in both browsers, leading to the use of "best viewed in Netscape" and "best viewed in Internet Explorer" logos that characterized these early years of the browser wars.
In 1995, Netscape Communications recruited Brendan Eich with the goal of embedding the Scheme programming language into its Netscape Navigator.
Before he could get started, Netscape Communications collaborated with Sun Microsystems to include in Netscape Navigator Sun's more static programming language Java, in order to compete with Microsoft for user adoption of Web technologies and platforms.
First, Brendan Eich and Mozilla rejoined Ecma International as a not-for-profit member and work started on ECMAScript for XML (E4X), the ECMA-357 standard, which came from ex-Microsoft employees at BEA Systems (originally acquired as Crossgain).
This led to working jointly with Macromedia (later acquired by Adobe Systems), who were implementing E4X in Action Script 3 (Action Script 3 was a fork of original ECMAScript 4).
