Javascript Introduction

JavaScript is the most popular scripting language on the Internet, it works with all major browsers, like Internet Explorer, Google Chrome, Mozilla FireFox, Safari, and Opera. JavaScript is a scripting language, this means, it is a lightweight programming language and everyone can use it without purchasing a license. It is usually embedded directly into HTML pages. It was designed to add interactivity to HTML, and it's scripts execute without preliminary compilation. The amazing this about Java and Javascript is that they are two completely different languages in both concept and design, which some of the newbies do not know. JavaScript is a scripting language with a very simple syntax. Almost anyone can put small "snippets" of code into their HTML pages. A JavaScript can be used to detect the visitor's browser, and - depending on the browser - load another page specifically designed for that browser. It can be used to store and retrieve information on the visitor's computer. JavaScript's official name is ECMAScript. The language was invented by Brendan Eich at Netscape (with Navigator 2.0), and has appeared in all Netscape and Microsoft browsers since 1996. The development of ECMA-262 started in 1996, and the first edition was adopted by the ECMA General Assembly in June 1997. ECMA-262 is the official JavaScript standard, which was approved as an international ISO (ISO/IEC 16262) standard in 1998. The development of the standard is still in progress.
