A very good introduction to AngularJS that will give a good overview of how the framework works, while providing concrete examples that showcase many of the things you can easily do with Angular. It would have been nice if the book went a bit deeper into how Angular works, but that was not in the scope of the book, so I believe the author accomplished his goals with this work.
This book is good for beginner to intermediate learners of the AngularJS platform. If you learn best by examples then this book is for you. If you like to 'code along' this book is for you with the exception that the css for the examples is not included so you will have a different looking product in the end but functionally the same. Since this is not a book on css but on Angular this is probably ok in my opinion.
