Preface

Over the past few years, Ext JS has become a popular and powerful JavaScript framework for desktop application development. For an Ext JS developer, the learning curve is not very easy/fast and I have seen cases where developers learning this framework find it to be a slow process. While writing this book I was thinking about the easiest and most comprehensible points so that you can understand the basics, just as I would have liked to learn about the framework if I was in your place.

This book is intended for developers who have the desire to learn and begin using this framework for their applications, and also for developers who have not started using the current version. It is written as an easy-to-follow guide that will help you understand the basics and fundamentals of the framework. If you have experience with previous versions of the framework, this book may clear many of your doubts about upgrading and how things happen in version 5.x.

This book covers all of the basic information you need to know to start development with this nice and powerful framework.
