The best book on going below the surface of Javascript

The author knows what he is saying. His style is like Bjarne Stroustrup in "The C++ Programming Language".
Although JavaScript is loosely typed and flexible, if you don't know the intention of each of its object and "type", your code will be a mess, and debugging on messy JavaScript code is painful. David Flanagan guides you to avoid that mess.
