I was very worried about reading this book, because its teaching approach is based only on cookbook and practically I had none knowledge prior about Ext JS. But really the author did an excellent job, even when is based on cookbook style this book practically was really useful to let me learn from the scratch Ext JS 3.0!.

I know, Ext JS 4.0 is already available and 3.3 release is legacy now, and even worst for 3.0, but you should consider none book about 4.0 exists yet and we have available Ext JS 3 to 4 Migration Pack, and I have checked many examples available on Ext JS 4.0 Samples, practically seems that critical changes about syntax from 3.0 to 4.0 are low. Of course new features are available for Ext JS 4.0 but I could suggest buy this book to learn quickly Ext JS 3.0 and be then ready to learn straightforward Ext JS 4.0.

Bear in mind, I have learned from the scratch Ext JS 3.0, the book has really available valuable chapters, each one covering interesting and realistic topics, refer to the TOC for a complete idea. The approach used for each chapter’s section is:

  • Topic (the case)
    • How to do it (code presentation, from very basic to complex, this complexity is easy to understand, I like this!)
    • How it works (code explanation)
    • There’s more (valuable reference)
    • See also (do reference to other topics covered in the same chapter to be read it, it is due because some variations among these topics exists, therefore exists a level of similitude and additions among them)

Furthermore output images are available for a better understanding, even many images to show the behaviour for some sample code are included

Therefore we have these chapters (I am including some topics to give you a better idea), refer to the TOC for the complete content

    • You can read the entire book comfortably
    • Easy to understand a 99% the source code throughout the book
    • action action and action!

    What I disliked:

    • In some few complex sample code sections, I felt the impression of a deeper explanation of the code.

    Conclusion:
