My Ruby book is explicitly modelled after K&R. The JavaScript book is also, though not quite so obviously. If you just look at the first 300 pages, the comparison would be more apt. Try to imagine K&R expanded to cover all of the major libraries that C developers have to use today. That would come out at over 1100 pages, too.
After you get through the first 5 chapters, you can kind of pick and choose what to read. Most chapters are 30-50 pages, and you should be able to work through them in an hour or two. Chapter 6, for example, covers objects (including ES5 extensions) comprehensively in 35 pages, and you'd probably come away after reading it feeling like you learned enough to make it worth your time.
If you read this book cover-to-cover (well, except for the hefty reference pages), you will be a JavaScript expert.
Thanks! That was my goal when writing it. It is about language mastery. Not so that you can answer quizzes about obscure corner cases, but so that you can program more effectively. Its like adding tools to your toolbox, and keeping them sharp.
If it's "The Definitive Guide", how can there be a 6th edition? I mean, a first edition would suffice if it was truly definitive...
Mod the parent up. This is funny!
