***(This book has been replaced by a new one from the same authors titled Learning Ext JS 3.2 and you should order that one and not this one)
I've been learning ExtJS now for a couple months and it's great to see someone has written a book for it. I just bought it and downloaded the E-Book version of it and from what I can tell it looks great. I'll post a more detailed review later, but for now, here is where you can get it.
Amazon.com: Learning Ext JS(Note: 2/11/09: I love this book. I still plan on writing a more detailed review, but for now, I thought I'd put a brief comment. I carry it around with me every where go (almost everywhere). It has great examples and great explanations -Peter)
