Popular JavaScript Framework Libraries: qooxdoo and SproutCore

Developing for the Web can entail a lot of workarounds, browser hacks and inefficient coding. When you think about it, why would you want to test your scripts for every grade A browser when you can use a JavaScript Framework to do the tedious work instead? Another reason to use a JavaScript Framework is to give your site a clean and professional look that would take you months to achieve on your own, if at all! This week we continue our overview of the top dozen Frameworks, with qooxdoo and SproutCore. If you've just encountered this series, you may want to go back to the beginning, where we looked at the Prototype, script.aculo.us and MooTools Frameworks. In the second installment, we turned our attention to three strong contenders for the title of Framework supremacy: JQuery, the Yahoo! UI Library (YUI) and MochiKit. In part three, we continued our overview of the twelve most popular JavaScript Frameworks in use today with Dojo, Rialto and the Spry Frameworks. This week's Frameworks are relative newcomers on the scene, but have already created quite a sensation.
