Its a really great Jquery book. I liked a lot the fact the authors simply let you see the power of jquery not getting too deeply into javascript. There is no cross/browser details or low level tricks.On the other side authors dont skip over important details.

Book has a very good structure and consistently presents Jquery API. I thik there is not much more you could expect from the book in that area.

I also loved the fact that they put javascript appendix to describe more complex ideas. It really gives you good review and puts all bits in place.

Finally examples are not bad and prepared urls let you play around to feel more comfortable with power of the library.

In summary, a great Jquery book. Must have for Jquery beginners and really worth to read even for non Javascript programmers just to get familiar with concepts and structure of one of the best libraries ever made :- )

Final score: 9.5/10
