Might also recommend Functional Javascript by Michael Fogus. He uses underscore.js, and avoids re-implementing classic functional patterns (map, reduce, filter, etc). I understood a lot of functional concepts from Lisp before reading the book. There might be something else you need first if you've had no exposure to FP, But if your basic FP-fu is good, this is a really nice book to read.
