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.
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
