Acknowledgments

A number of people have helped me in shaping this book.

First of all, I have to thank all the developers I have interacted with during my talks and consulting assignments for the last 2 years. The discussions with them made me understand the concepts of Ext JS 4 better. Some of the comments contributed by readers of my blog posts offered good insights into the framework.

I would like to thank my technical reviewer Massimo Nardone, whose comments and troubleshooting, particularly in the code examples, have been really helpful in shaping this into a better book.

Writing a book is not easy. It eats up your time, as it involves a lot of focus. I would like to thank my manager and friend Siva at DuraSoft for being extremely accommodating and encouraging all through.

Lastly, I would like to thank the team at Apress for being thoroughly professional throughout. It was a pleasure working with you all.
