Where can I find information about Javascript engine internals? [closed]

Answer 1

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 )

Answer 2

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 3
