This book would be a great start for anyone wanting to learn jQuery. It give a basic overview of how jQuery works and then continues on to dig deeper into the functionality provided by jQuery. I liked this book for the useful examples it provides along the way. Every piece of code you need in order to complete the task is ready and available through the recipes. I found that there were some simple things in jQuery that I wasn't using in my development, things that I could have been using all along but hadn't taken the time to discover via the documentation. This book helped to show me how some of this functionality can be put to use. I especially appreciated the section on form handling as it's highly relevant to work I do. However I would have hoped to see some mention of preferred plugins to use in the footnotes. I also found that some references may be advanced for beginners but the additional explanations on the same page help along the way. Careful as some of the practices used in the examples aren't necessarily "best practices" so use your best judgement on what works in your current situation. Recommended in this book are the sections on plugin development, jQueryUI and jQuery Mobile.
