Find whatever works for you to reach "mediocre proficiency" then use that to improve until you reach "perfect and complete level". You won't find any resource for any language that will hold your hand all the way, if only because the concept of "perfect and complete" is rather fuzzy and subjective (and probably a moving target for a language like JS that's still in active development). JS is a rather forgiving language (maybe too forgiving) that's very suitable for learning by trial and error. Get the basics, start hacking, find what works and what doesn't, look at other people's code to draw inspiration etc...
