Definition: JavaScript is an active scripting language created by Netscape based on Sun Microsystem's platform-independent programming language Java. Originally named LiveScript, Netscape changed the name to JavaScript to ride on the coattails of Java's popularity. JavaScript is used within HTML to execute small programs to generate a dynamic web page. Using JavaScript a developer can make text or graphics change when the mouse points at them, update the current date and time on the web page or add personal information like how long its been since that user last visited the site. Microsoft Internet Explorer supports a subset of JavaScript dubbed JScript.
