Pro JavaScript Techniques

Pro JavaScript Techniques provides everything you need to know about modern JavaScript. This book focuses on fundamental, vital topics--what modern JavaScripting is (and isn't), the current state of browser support, and pitfalls to be wary of. It is organized into four distinct sections, each of which features several real-world examples. JavaScript usage on the Web has changed in recent times, due to increased JavaScript support in web browsers, and new techniques coming to light. JavaScript is also now being looked on as a proper programming language, whereas in it's inception it was regarded as little more than a scripting toy.
This book addresses all the points above in detail - modern browser support (including information on Internet Explorer 7), Object-Oriented JavaScript, testing and debugging, Unobtrusive JavaScript techniques using DOM Scripting, Ajax, creating and using blocks of reusable code, and looking towards the future of JavaScript.
It backs up all the concepts with real world examples and full-blown case studies, and also includes several reference sections to allow developers to look up details quickly and easily.
