UserScripts in 20 Minutes (Coffee Book Series)

Strong content, uneven pacing. I would still recommend it.

I had been on the fence about this one for a while, and I should have bought it sooner. The author avoids over-explaining, which keeps the pace up but means you need to pay attention. The balance between theory and practice is well judged; neither side dominates. Four stars, and I suspect a second edition could easily push it to five.

Good value. Not perfect, but I would buy another book from this author.

A colleague recommended this and I can see why. It does something that few technical books manage: it respects the reader's time. The code samples assume a particular environment, which took a bit of fiddling to get running properly. I particularly liked the way the author builds up from simple cases before introducing the harder material. The author avoids over-explaining, which keeps the pace up but means you need to pay attention. Recommended, with the caveat that it is not a gentle introduction.

Not quite what I expected from the description, but there is material here.

This is the third book I have read on javascript this year, and it is comfortably the best of them. A couple of chapters felt like they could have been merged, but that is a minor complaint. The book rewards careful reading. Skimming it would be a mistake. Borrow it first if you can, or at least check the table of contents carefully before buying.
