Changes in JavaScript

There are many new features in HTML5, but the biggest change is really in the way that Web pages are used. The Web is no longer simply about hosting documents, but it is becoming an application-development framework. Some of the most interesting and potentially far-reaching innovations in HTML5 are in the new additions to JavaScript available in modern browsers.

JavaScript has emerged as a critical technology for modern Web applications, and every browser has improved the performance of the JavaScript engine in recent years. In addition, a number of fascinating new extensions to the JavaScript language are becoming available.

This part focuses on those aspects of JavaScript that are especially intriguing and new. I assume you have some familiarity with computer programming and the JavaScript language. If you need a refresher, please check my book titled JavaScript & AJAX For Dummies (Wiley).
