I think "JS: the good parts" is a great book, I actually had the pleasure of serving as technical reviewer and read drafts of the book. I like Douglas Crockford's work, presentation methods and sense of humor I'm proud that he's also one of the technical reviewers of my book.
The thing with his book is that it's a pretty advanced book, he assumes you already know quite a bit and you're at the stage where you're interested in best practices and such. So I consider my book a sort of a pre-requisite for his. But if you've enjoyed his book, maybe you don't need the pre-requisite.
That said, his book is exactly 100 pages before the appendices and mine is 300+ so there must be things, besides the basics, that I talk about and he doesn't. Mine definitely has more about different approaches to inheritance, giving you the base with a dozen ways and letting you think of more. I also talk more about the browser, chapter 7 is about the browser - BOM, DOM, Ajax. In chapter 8 I discuss design patterns which I don't think Doug's book does.
Thank you for your reply. Yeah, I really enjoyed the condensed, to-the-point nature of the book. But the reference-with-examples part of your book sounds especially interesting. I'll make sure to check it out!
