JavaScript has changed a lot since. The way we do asynchronous computation (callbacks -> promises and coroutines), the idioms we like/hate, the runtime performance penalty of different styles. It's true that crockford, javascript-allonge and JS Garden are all good resources but they are simply not as up to date as YDRNJS and they're not as covering. This book doesn't cover 'with' in depth or anything like it. It explains idioms that have formed since "The Good Parts" came out - that was a long time ago and a lot happened since.
