Who is this book written for ?

Knowledge of JavaScript and jQuery as well as basic experience with frontend development is all you need to start making games in a matter of hours with this essential guide. Whilst also suitable for those who simply want to start making games with jQuery, it's specifically targeted at web developers that want to experiment with and utilize their existing skills.

I know javascript but never used jQuery, will I still understand the book ?

Even though a lot of the techniques described in the book apply to vannila Javascript some parts requies basic knowledge of jQuery. But learing jQuery through a simple tutorial and reading throught the first chapter of this book should provide you with all the knowledge you need about jQuery.

I want to learn how to use gameQuery, should I read this book ?

This book is not about gameQuery but it answers a lot of the game development questions I encounterd from gameQuery's users during the last years. You won't learn gameQuery but you will create your own framework that has most of the basic functionality of gameQuery. Translating the knowledge you gained from this book to gameQuery should be a walk in the park!

Games, using jQuery, really ?

Using jQuery and the DOM to create games may not seam like the most straight forward ways of doing thing but it has several advantages. I think it's a very good way for a beginer to approach game developement since it abstarct all the dirty business of dealing drawing pixels. Furthermore a lot of what you learn in this book will be useable with other rendering techniques such as Canvas or WebGL.
