As for a course, I would definitely say that Dan Abramov's JustJavaScript teaches you not only what you can do in JS but also WHY. You can check out the free preview to see if it works for you. Dan Abramov is a co-creator of Redux and has been a member of the React core team for the past few years.
If you like books, I'd recommend Elegant JavaScript and You Don't Know JS. Both are free. However, it's more trivia knowledge so don't kill yourself with it.
I'm definitely with you all on the Mozilla docs.
