Preface

In the world of Rich Internet Applications (RIA) development, Ext JS stands out as a cross-browser JavaScript library that offers the applications developer a powerful toolset. With a set of customizable user interface widgets similar to those found in desktop operating systems, an effective data binding model, a comprehensive programming interface for manipulating the Document Object Model and communicating with the server, a committed development team, and an enthusiastic users' community, the Ext JS library is a great choice for today's web builders.

This book addresses many of the library's features, from the perspective of how they can be used to solve the real-world challenges faced by those that develop internet applications.
