What is Javascript?

A Scripting Language developed by Netscape that runs via a Web Browser. It's uses are both numerous and powerful, from simple scripts to check the data being passed to a form to more complex scripts that form the basis of Web 2.0 technologies such as Ajax used for things such as displaying a full representation of a Desktop Interface or a Word Processor in a Web Browser.


Not to be confused with Java which is different kind of programming language that only shares a name because Netscape chose to name JavaScript after it to help gain popularity for their new language.
