jQuery has made JavaScript development easier, and helped many developers build powerful applications quickly. Sometimes, though, you need to go beyond jQuery - because you need to work with someone else's code, because you need something smaller and lighter-weight, or because you need to go beyond what jQuery can do. This book will show you how to build on your core jQuery skills and go much further into JavaScript itself, examining event handler, function declaration, JavaScript patterns, and the DOM.

If you’re comfortable with jQuery but a bit shaky with JavaScript, this concise guide will help you expand your knowledge of the language—especially the code that jQuery covers up for you. Many jQuery devotees write as little code as possible, but with some JavaScript under your belt, you can prevent errors, reduce overhead, and make your application code more efficient.

This book explores event handling, prototypes, and working with the DOM and AJAX through examples and lots of code. You’ll learn common conventions and patterns in JavaScript and—if you’ve never coded with JavaScript before—a tutorial will take you through the basics.

Enhance your jQuery code by using object constructors and prototypes
Reduce overhead and gain more control by handling events with JavaScript
Work with the DOM much faster with JavaScript than you can with jQuery
Send a few AJAX requests without having to load the entire jQuery library
Understand the importance of JavaScript code standards, comments, code reuse, and anti-patterns
Enlist JavaScript resources, such as a good IDE, a syntax checker, and version control

Callum Macrae is a professional JavaScript developer based in the UK. He regularly contributes JavaScript related patches to open source projects, including phpBB and the Hex IRC bot. When not coding or writing, he spends most of his time drumming or playing the piano.
