Javascript Bible is a huge paradox, and a huge disappointment. I'm the typical purchaser of the book--HTML-literate looking to learn Javascript. It came highly recommended, so I immediately purchased it. In retrospect, I should have bought Javascript Sourcebook instead--I learned HTML with that superb "Sourcebook" series, and i should have stuck with it. The Javascript Bible starts off promising for the beginner, and introduces JS well. But it then jumps into hundreds of objects and functions and doesnt explain their context and placement. I was lost. Another reviewer here said you'll get lost after Chap4--boy, is he ever right! After Chap4, the inexperienced JS programmer will be absolutely befuddled and clueless. To its credit, the book offers lots of code examples; but it doesn't explain how and why the code was written. I'm very disappointed. In short, if you've never programmed in JS before, this book won't teach you. No way.
