MooTools is a JavaScript framework that enables you to write clean, concise, reusable code to animate and dynamically change the content on your site using Ajax and other technologies, taking care of all the grunt work for you. This book aims to make the process of getting started with MooTools an easy one, covering everything from downloading the code and adding it to your pages to explaining what each class and method does (and, perhaps more importantly, when you’ll use each one).
