I've read it as well, it was at least as good as Effective Java. One thing that's interesting about the book is that while he mentions things like "don't use feature X, works strangely in some browsers", he never explicitly states which browsers. He also doesn't make a lot of mention to frameworks etc, or the DOM. Just the common denominator javascript as it is implemented, and the language features. So don't expect it to teach you the latest tricks in your favorite MVC framework. It's written in a very timeless way on purpose, and he very deliberately avoids making reference to "current events" in javascript.
