Many would initially think that Javascript has something to do with Sun Microsystem’s Java but as the matter of fact, it doesn’t. Javascript was created by Netscape, they previous name was LiveWire, then LiveScript.

Javascript is a programming language that is normally used on the client side. It is easy to learn and pick up. Most Javascripts on websites serve the purpose of encouraging user experience, increase interactivity, functionality as well as web speed. DHTML (Dynamic HyperText Markup Language) is formed with the use of Javascript and CSS (Cascading Style Sheets). On the other hand AJAX (Asynchronous JavaScript and XML) is Javascript based web development technique that uses data formatted in XML.

Here are some good Javascript sites that worth a visit.

5. Ext Javascript Library

   

   Ext is a client-side, JavaScript framework for building web applications. In early 2006, Jack Slocum began working on a set of extension utilities for the Yahoo! User Interface (YUI) library. These extensions were quickly organized into an independent library of code and distributed under the name “yui-ext.” In the fall of 2006, Jack released version .33 of yui-ext, which turned out to be the final version of the code under that name (and under the open source BSD license). By the end of the year, the library had gained so much in popularity that the name was changed simply to Ext, a reflection of its maturity and independence as a framework. A company was formed in early 2007, and Ext is now dual-licensed under the LGPL and a commercial license. The library officially hit version 1.0 on April 1, 2007.

   Dojo is an Open Source DHTML toolkit written in JavaScript. It builds on several contributed code bases (nWidgets, Burstlib, f(m)), which is why we refer to it sometimes as a “unified” toolkit. Dojo aims to solve some long-standing historical problems with DHTML which prevented mass adoption of dynamic web application development.
