JavaScript, The Definitive Guide

Written by David Flanagan and published by O’Reilly Media, this is an exhaustive reference to the JavaScript language. Not for the faint of heart, this is where the experts turn to look up those weird operators and nail down that odd syntax. The 5th Edition of this book (the latest available as we write) is more than two years old and covers JavaScript 1.5, but it’s still a valuable reference.
