(*and even the bad parts)
At Yahoo! I had the privilege of working directly with Doug Crockford and got to review a book he was writing at the time, Javascript The Good Parts.
This book is different than most other Javascript books. It just focuses on the language itself and not the browser DOM. It reveals both gems and warts. And it does it in a simple straightforward manner. It reminds me of the classic The C Programming Language book that I cut my teeth on.
This is a must for your bookshelf.
You can get JavaScript: The Good Parts at Amazon.
