This book would not have been possible without the support and encouragement of so many people. I can't possibly name them all, but there are few who come instantly to mind: the editorial team at Packt Publishing, everyone at Dealer.com for listening to me ramble about this stuff, Jonathan Phillips for being my first JavaScript mentor, Mike Fogus for showing the way, Amy (my wife and partner-in-crime) for giving me the space, and my sons Holden and Emery for every little worthwhile distraction.
