Javascript

JavaScript is a programming language that is mostly used in web pages, usually to add features that make the web page more interactive. When JavaScript is included in an HTML file, it relies upon the browser to interpret the JavaScript.

According to Wikipedia, one major use of web-based JavaScript is to write functions that are embedded in or included from HTML pages and interact with the Document Object Model of the page to perform tasks not possible in HTML alone. Here are some of the most common uses of JavaScript:

Opening or popping up a new window with programming control over the size, position and ‘look’ of the new window
Validation of web form input values to make sure that they will be accepted before they are submitted to the server
Changing images as the mouse cursor moves over them
