JavaScript is an object scripting language used in HTML with the markup language HTML. JavaScript is very popular and is universally adopted by every web browser for its support to enable dynamic content to be played on a web page. JavaScript does not contain or comply with any HTML tags or rules. It is similar to the independent programming language developed by Sun Microsystems. As JavaScript gained worldwide success with its integration into web browsers, Microsoft added JavaScript technology to its own browser Internet Explorer.<\/p>\n\n\n\n
JavaScript was a scripting language developed by Brendan Eich of Netscape; initially, it was named Mocha, later LiveScript, and finally JavaScript. In December 1995, Sun Microsystems and Netscape announced JavaScript in a press release. In November 1996, Netscape announced a meeting of the Ecma International standards organization to advance the standardization of JavaScript. The first edition of ECMA-262 was adopted by the Ecma General Assembly in June 1997. Several editions of the language standard have been published since then. <\/p>\n\n\n\n
Meanwhile, Microsoft\u00a0debuted\u00a0Internet Explorer\u00a0in 1995, leading to a\u00a0browser war\u00a0with Netscape. On the JavaScript front, Microsoft\u00a0reverse-engineered\u00a0the Navigator\u00a0interpreter\u00a0to create its own, called\u00a0JScript. Microsoft initially participated in the standards process and implemented some proposals in its JScript language, but eventually, it stopped collaborating on ECMA work. Thus ECMAScript 4 was mothballed.<\/p>\n\n\n\n
The standards process continued for a few years, with the release of ECMAScript 2 in June 1998 and ECMAScript 3 in December 1999. Work on ECMAScript 4 began in 2000.<\/p>\n\n\n\n
During the period of\u00a0Internet Explorer\u00a0dominance in the early 2000s, client-side scripting was stagnant. This started to change in 2004, when the successor of Netscape,\u00a0Mozilla, released the\u00a0Firefox\u00a0browser. Firefox was well-received by many, taking significant market share from Internet Explorer.<\/p>\n\n\n\n
In 2005, \u00a0Mozilla joined ECMA International, Jesse James Garrett\u00a0released a white paper in which he coined the term\u00a0Ajax. Many new libraries were created, including\u00a0jQuery,\u00a0Prototype,\u00a0Dojo Toolkit, and\u00a0MooTools.<\/p>\n\n\n\n
Google\u00a0debuted its\u00a0Chrome\u00a0browser in 2008, with the\u00a0V8\u00a0JavaScript engine that was the first to use\u00a0just-in-time compilation, significantly improving execution times.\u00a0Other browser vendors needed to overhaul their engines to compete.<\/p>\n\n\n\n
In July 2008, these disparate parties came together for a conference in\u00a0Oslo. This led to the eventual agreement in early 2009 to combine all relevant work and drive the language forward. The result was the ECMAScript 5 standard, released in December 2009.<\/p>\n\n\n\n
While both JavaScript and JScript aim to be compatible with ECMAScript, they also provide additional features not described in the ECMA specifications.<\/p>\n","protected":false},"excerpt":{"rendered":"
