Mat consistently demonstrates empathy for you (his reader), your users, and the future maintainers of your code, making this book a great companion for any web designer looking to take on more programming responsibilities.

JavaScript is here, in full force. You hold in your hands a book that clearly explains the essentials you really need to know. Mat will teach you how to write running code for real websites and give you a firm grasp on JavaScript's building blocks.

When I first tried learning JavaScript, I gave up, deciding it was impossible. It was only a year later that I went back, gave it another go, and started to get it. This book would have saved me that year. It covers not only understanding JavaScript, but also how to use it responsibly within the browser. You won't find that in many other books, which is why there are so many bad experiences on the web.
