BOOKS FOR PROFESSIONALS BY PROFESSIONALS ® Pro JavaScript with MooTools Pro JavaScript with MooTools is unlike any other JavaScript book on the mar- ket today. While similar books focus on either JavaScript as a language of the browser or how to use JavaScript frameworks, Pro JavaScript with MooTools fills the gap between these topics and moves beyond—exploring the advanced features of JavaScript and how the MooTools framework uses these features to further improve the language itself. The book itself takes a unique three-pronged approach. It first walks you through the advanced features of JavaScript and the MooTools framework, including native augmentation and type creation, a comprehensive discussion of JavaScript functions, object-oriented programming with native JavaScript and MooTools Classes, and the MooTools Class internals. You’ll then learn all about JavaScript in the DOM: the Elements Class and its internals, the MooTools Event system, Selector engines and MooTools Slick, Ajax and the Request Object, and Animation and the Fx classes. The final section really sets the book apart from all others, as it discusses JavaScript outside the browser. You’ll take an in-depth look at CommonJS and MooTools, using MooTools outside the browser using Meso, and creating CommonJS web applications via the MooTools Deck framework.

library or a JavaScript framework Though these descriptions aren’t necessarily wrong, they don’t encapsulate the main idea behind MooTools which is to leverage and improve the JavaScript language itself Therefore, I prefer to call MooTools something else: a language extension Developers using MooTools are expected to be JavaScript programmers first, MooTools. .. writing awesome JavaScript and MooTools material for years, in articles (like his “Up the Moo herd” series) and in actual code (Raccoon!) His blog is a mustread for anyone wanting to learn or expand his knowledge of MooTools, or JavaScript in general Pro JavaScript with MooTools isn’t simply a well-written technical book This book thoroughly explains how object-oriented programming works in JavaScript, ... computer, and some you can easily download for free So without further ado, here are the components of a JavaScript developer’s toolkit 5 www.it-ebooks.info CHAPTER 1 ■ JAVASCRIPT AND MOOTOOLS JavaScript Interpreter A JavaScript interpreter (or engine) is a program that parses and executes JavaScript programs You’ll need an interpreter that implements at least JavaScript version 1.5, which is equivalent to... the MooTools community could share their code And with the release of version 1.3, MooTools has once again reinvented itself with a simpler Type system, an improved Class implementation and a fast new selector engine From its 3 KB beginnings as an effects library, MooTools has grown into one of the best and most powerful JavaScript frameworks around The Language Extension MooTools complements JavaScript. .. really at times Fortunately, that’s where this book comes in Pro JavaScript with MooTools will take you on a journey from the building blocks of JavaScript, through the prototypal concepts, to the very inner workings of MooTools By the time you’re finished reading it, MooTools will hold no more secrets from you When I think about the best MooTools articles I have ever read on the Web, Mark’s blog, Keetology,... second In the MooTools community, a lot of emphasis is given to learning how to properly write JavaScript, and everyone is expected to know at least the basics of programming This is because MooTools itself is so intertwined with JavaScript that learning the framework without having a basic grasp of the language would be impossible What’s often surprising for new users is just how much MooTools feels... native counterpart for working with web documents MooTools makes the process of working with JavaScript easier on so many levels and it inspires developers to add more features to the language In the chapters that follow you’ll see just how much MooTools complements the language While this is primarily a JavaScript book, MooTools is used as an exemplar of what’s possible with the language, and how you—using... their quirkiness This book is about JavaScript as it relates to the MooTools framework Like any other language, JavaScript s predictability has a lot to do with the people who code with it While it is pretty predictable, JavaScript does have some quirks and unique features that might not be apparent at base level Unfortunately, a lot of us who proudly proclaim to be JavaScript developers don’t take time .
