Those who know me shouldn’t be surprised that this book is more than just an update. The 3rd edition features five completely new chapters covering the new HTML5 APIs such as history state managements, canvas, offline applications, web workers, and more. Throughout the book, I’ve added references to changes in ECMAScript 5, including how strict mode works and how to use the new object-creation APIs. All of the existing chapters were also updated with the latest browser support information including mobile support (sadly, that will always be a bit out-of-date). A special appendix about ECMAScript Harmony is also included to give you a taste of the future.
I’m also incredibly honored to have a foreword written by Rey Bango. Rey had so many kind words about the 2nd edition that I was thrilled when he agreed to write the foreword for this one. And here it is:
I look back at my career (now 20+ years) and in between coming to the realization that my grey hairs
have really sprouted out, I reflect on the technologies and people that have dramatically affected
my professional life and decisions. If I had to choose one technology, though, that has had the single
Like many, I looked at it as a play language relegated to doing rotating banners and sprinkling some
interesting effects on pages. I was a server-side developer and we didn’t play with toy languages, damn
it! But then something happened: Ajax.
I’ll never forget hearing the buzzword “Ajax” all over the place and thinking that it was some very cool,
new and innovative technology. I had to check it out and as I read about it, I was floored when I realized
that the toy language I had so readily dismissed was now the technology that was on the lips of every
professional web developer. And suddenly, my perception changed. As I continued to explore past what

team and focusing on client-side development. Life was good.

And the book felt genuine and thoughtful, as if Nicholas understood that his audience’s experience
level would vary and that he needed to manage the tone accordingly. That really stood out in terms of
technical books. Most authors try to go into the deep-dive techno-babble to impress. This was different

starstruck when I met him and the great thing is that he was just this incredibly down-to-earth person
who just wanted to help developers be great. So not only did his book change the way I thought about

transition from introductory topics such as expressions and variable declarations to advanced topics
such as closures and object-oriented development is what sets it apart from other books that are either
the “every man’s” book that will help you write code that you’ll be proud of and build websites that will
excite and delight.

I hope that Rey, and all of you, enjoy the 3rd edition just as much as (if not more than) the 2nd edition. The book is available for purchase at Amazon and available for download as an ebook from Wrox.
