Legendary book, a must-read for any Javascript programmer at least once. Goes into the basics of Javascript with the assumption that the reader is an experienced programmer already, coming from another language or already understands a fair bit about Javascript itself. Very good review of basics and more advanced concepts (like scope/closure, functions as first class objects, etc).
