All Packt Publishing Cookbook Series books are meant to be read without procedural constraint. That means, we can open any page in the book and just start mooing. This book, being a cookbook, follows that crucial precept while also harboring a secret agenda to move from smaller concepts to larger concepts for the benefit of any potentially existing procedural readers. Those of us that may be new to these concepts will benefit greatly from this chapter.
MooTools was conceived by Valerio Proietti and copy written under MIT License in 2006. We send a great round of roaring applause to Valerio for creating the Moo.FX (My Object Oriented Effects) plugin for Prototype, a JavaScript abstraction library. That work gave life to an arguably more effects-oriented (and highly extensible) abstraction layer of its own: MooTools (My Object Oriented Tools).
Find more information about Moo.FX at http://moofx.mad4milk.net/. The link labeled GET MOO.FX FOR MOOTOOLS leads us to MooTools, which is exactly what we are delving into; so we continue, confident that with MooTools, we are getting what Moo.FX has become.
