Until recently, French literature about MooTools was pretty much non-existent. Thanks to Xavier Lecomte, now there is a very good book about MooTools in your native tongue that will get you up to speed in no time.
As the author says, it does not cover the entire framework. Instead, Xavier Lecomte selected the most commonly used MooTools pieces and explains them in detail. Throughout this book, you’ll learn how to create classes, handle DOM elements, create AJAX requests and create effects using Fx classes. The latter is probably the most discussed topic of this book as it goes through almost every Fx-based class in MooTools. When it comes to Fx classes, the most complex part is probably options. Although they are well named, they could be difficult to grasp, especially to the novice user. This book makes this type of functionality very clear by explaining all the options for each class discussed, at times, through the use of illustrations. The Fx chapter wraps up with a complete example, where the author builds a pong game using tools explained throughout the chapter.
Finally, the book discusses work done by the MooTools community. Although it does not go deeply into each project (most of them would require a book on their own), it gives a good idea of what MooTools is able to offer.
To conclude, if you’re a native French speaker interested in learning MooTools, this book is a must-have, especially at that price. I hope Xavier Lecomte will continue writing about MooTools, the in-depth detailing of this book is amazing and will certainly benefit many.
