First, a big thank you to my partner Beci, who, now that the book’s fi nished, will get to see me for more than 10 minutes a week. I’d also like to say a very big thank you to Maureen Spears, who has worked very effi ciently on getting this book into print. Thanks also to Jim Minatel for making this book happen. Many thanks to everyone who’s supported and encouraged me over my many years of writing books. Your help will always be remembered. Finally, pats and treats to my German Shepherd Dog, Katie, who does an excellent job of warding off disturbances from door-to-door salespeople.

First and foremost, a huge thank you to my wife for putting up with my late nights. Just as huge thanks go to the people at Wiley Publishing: Jim Minatel and Scott Meyers for making this happen; Maureen Spears who was absolutely wonderful to work with in getting this book into its fi nal, printed form; and David M. Karr for keeping me honest. Lastly, thank you Nicholas C. Zakas, author of Professional JavaScript, 2nd Edition (Wiley 2009) and co-author of Professional Ajax, 2nd Edition (Wiley 2007), for getting me into this business.

Whom This Book Is For 

To get the most out of this book, you’ll need to have an understanding of HTML and how to create a static web page. You don’t need to have any programming experience. This book will also suit you if you have some programming experience already and would like to turn your hand to web programming. You will know a fair amount about computing concepts, but maybe not as much about web technologies. Alternatively, you may have a design background and know relatively little about the web and computing concepts. For you, JavaScript will be a cheap and relatively easy introduction to the world of programming and web application development. Whoever you are, we hope that this book lives up to your expectations.
