review 1: Pretty good reference. I think the book's age (references IE4) actually helps it in some ways, as it discusses guidelines and practices for improved performance on browsers much less powerful than we have now. Most developers should be familiar with the majority of this book (script placement, sync vs async, caching, etc.) but there were plenty of other interesting topics, such as real-world use cases bitwise operators and Duff's device.
review 2: A disappointment, but mostly due to its age. When a book features performance testing of Google Chrome versions 1 and 2, you know something's off. Finally forced myself to finish reading it, but found little of value in the back half of the book. The problem is that almost everything in the book is a well-established ... morebest practice now, and if you're even moderately up-to-date on writing good JavaScript, the book is almost all repetition.That said, the big payoff was Chapter 3. Here is where the DOM interaction comes into play, and the ideas of repainting and reflowing the page were examined. There are also some interesting parts in Ch 5 (regexes) and 6 (timers) if you're not already familiar with the performance aspects of those features.I'd recommend intermediate and some advanced JS folks to skim certain chapters; just watch out for the speed tests -- use jsperf.com instead! less
