A subset of the overlying JQuery framework, this book is at the more concise offspring textbook that provides good coding examples in aiding in the process of creating web mobile apps. Even if you don't have a strong JQuery background, learning by example, doing what you want to do through a mobile-focused book is perfect for you, as it was for me. I use it as a reference but will follow more of the examples as need be, but some things you may get lost of if you don't hold some grasp of JQuery. It did derail me a little but i just picked up some interesting web links to help me with those concepts, if i got stuck on a particular section. Overall I enjoyed the style of Jon Reid, and would certainly recommend this book, as part of your development arsenal.
