I do this stuff at work so I was amazed at the high selection of usable recipes. I was actually intending to purchase a CSS3/Layout book, but I just can't get excited about a book for something like that and was excited to see some of that covered in this book.
It's impossible to have projects take you in to every "possible" area in front end web dev, and this book seems to cover a lot of ground. Perhaps I'm a bit early to rate this as I'm only 1/3 through the book, but I'm giving it 5 stars just on what I've read so far + relevance. I have read other pragmatic recipe books that I thought were just ok but this one is better. Again, I do this stuff for a living and I can assure that the choices made are pretty darn good (e.g. knockout and backbone; ok, you can go learn Ember, etc., yourself, but I've tried all the MVC's to date and these are quite reasonable choices). Also, stuff that I DO know already I can confirm that they're advise is pretty spot on.
Disclaimer: Assumes you're relatively experienced (although a determined beginner could google missing info). Also, the book is very time sensitive in that many recipes will become obsolete in time but what else is new! Also, as someone who's reasonably experienced, I'm not so worried if there are typos/mistakes and I'm a bit more interested in concepts that will bootstrap me in the right direction. Lastly, if you prefer full coverage of topics, rationale, etc., this book is likely not aimed at your needs; although you may still consider it as a supplementary material to a thicker reference, etc. If you get bored with long winded books, however, this one's probably a fit. It's sort of a "written by developer's, for developers" approach they take.
