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

I was curious about this too, and here's what I found:

About Chrome's Javascript engine (v8):

• Garbage Collection in V8; For mobile and beyond
• V8 Internals: Building a High Performance JavaScript Engine
• Chrome V8 - Design Elements

About Firefox Javascript Engine (Spidermonkey):

• Spidermonkey Internals
• Spidermonkey is on diet
• IonMonkey: Mozilla’s new JavaScript JIT compiler
• Tracemonkey (obsolete JIT compiler, but however the article is still interesting)

About IE 9+ Javascript Engine (Chakra):

• Advances in JavaScript Performance in IE10 and Windows 8 - Internals of Chakra

About Safari Javascript engine (SquirrelFish):

• Announcing SquirrelFish
• Introducing SquirrelFish Extreme

• The Future of JavaScript Engines: Replace Them With JavaScript Compilers

Answer 3

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 )
