JavaScript is increasingly seen as a proper application language instead of just a tool for spicing up web pages. Ext JS, a mature and stable JavaScript framework, provides the libraries and structure needed to write desktop-quality applications for the browser. Because Ext JS elegantly manages much of the boilerplate associated with web development, it minimizes the tedious hand-coded HTML. Ext JS saves time, helps developers write better apps and stay standards-compliant. Ext JS in Action, Second Edition teaches Ext JS from the ground up. It starts with a quick overview of the framework and then explores the core components by diving into complete examples, engaging illustrations, and crisp, straightforward explanations. It's like having an expert guide right at your elbow, teaching you important Ext techniques and offering insight into its inner workings.
