Javascript is a simple scripting language used to enhance web pages. Although Javascript can also be used on the web server, its use is most common as embedded scripts in HTML pages to be executed in the web browser. The Javascript language only slightly resembles the Java language and has no further connection to Java.

Javascript code is often executed in response to mouse clicks or other actions from the user and, as such, improves the interactivity of web pages. Care must be taken, however, not to over use Javascript on your web pages as different web browsers may interpret the Javascript code differently, which often results in the dreaded "Javascript Error" message.
