JAVASCRIPT



JavaScript, often abbreviated as JS, is a programming language that conforms to the ECMAScript specification. JavaScript is high-level, often just-in-time compiled, and multi-paradigm. It has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions.

JavaScript is a client scripting language which is used for creating web pages. It is a standalone language developed in Netscape. It is used when a web page is to be made dynamic and add special effects on pages like rollover, roll out and many types of graphics.

The JavaScript language itself, as a format, is free, and use of JavaScript in a web site is not necessarily bad.

"The language's name is the result of a co-marketing deal between Netscape and Sun, in exchange for Netscape bundling Sun's Java runtime with their then-dominant browser." It was originally called Mocha, renamed to Live Script, and then renamed to JavaScript.
