One good book leads to another.

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

This is the third book I have read on javascript this year, and it is comfortably the best of them. The chapters on javascript are the strongest — the examples are stripped down but complete, and I could follow along without constant guessing. It is denser than the page count suggests, and I found myself slowing down around the middle. Worth picking up if you already have the basics. Set realistic expectations and you will get a lot out of it.

Genuinely excellent — I finished it in a week and immediately started again.

A colleague recommended this and I can see why. It does something that few technical books manage: it respects the reader's time. The writing is direct and does not waste space on filler, which I value in a technical book. The writing is direct and does not waste space on filler, which I value in a technical book. I found myself making notes in the margins, which is always a good sign. An easy five stars from me. I look forward to whatever the author writes next.

Outstanding. I kept finding reasons to come back to it.

I bought this on a whim after seeing it mentioned in a forum thread, and I am glad I did. Some of the material is available elsewhere, but rarely presented this clearly. A few of the examples could be more realistic, but the underlying points come across clearly. There is a section near the end that ties several earlier ideas together in a way I had not seen before. This is the book I wish had existed when I started working with databases & big data.
