It is not really a book but I find resources on mdn very helpful https://developer.mozilla.org/en-US/learn/javascript https://developer.mozilla.org/en-US/learn/javascript Besides tutorials on mdn they have included links to some of the best javascript resources on the internet and classified them according to the level of the individual.
