For those not familiar with Murach books, they all follow the same format, so once you’ve read one you’ll know whether they work for you or not. The books use a “paired pages” format with syntax and examples on the right, explanation on the left. This helps make the books useful to people of different experience levels: you can scan the pages on the right until you see something you need to know more about, and then read the left page for that topic.
I found the book to be well-edited and easy to follow. As expected, it starts with the basics and runs through advanced topics like closures, finishing with a short chapter on when and how to use jQuery (although I’m not sure I’d agree with the assertion that you should use jQuery whenever you can – why add the overhead of including a library just to save a few lines of coding?)
Disclosure: I received a free review copy of this book.
