Where can I find information about Javascript engine internals?

Question

I'm looking for books / articles / papers on Javascript engine internals along the lines of the many reference works about the JVM internals, CLR internals, etc. I could (and likely will) look at the source code for JavaScriptCore and V8/Chromium, but if there's a book out there or some other "guided tour" documentation, I'd prefer to read them first. Thanks.

Answer 1

One of the in-depth documents could be the ECMA-262 Language Specifications.

A good book on the language's idioms and best practices is JavaScript The Good Parts

Answer 2

Google have documented a lot about V8. http://code.google.com/p/v8/ There are some interesting videos on the main page ( although you've probably already seen those )
