I've shipped very little JS code, so take this with a grain of salt. However I have had to ship JS code, and since I'd heard horror stories, I tried to find some solid resources to make sure I wasn't shipping garbage. I found these really helpful:
Eloquent JavaScript, a freely available book with an in-browser REPL and a lot of fun exercises
Douglas Crockford's JS master class, which covers a lot of the same material as his "JavaScript: the Good Parts" but in video format, and I think in a much more digestible way. The Good Parts book is very, very dense and probably best used as a reference. (why he thought starting with a formal definition of the langauge's grammar was a good idea completely escapes me)
I don't actually know if these are really up-to-date, and all the cool kids are using CoffeeScript anyway, so anyone with more experience please correct me if these aren't any good. They definitely point out how to avoid the most painful quirks of the language, and how to leverage the core that is actually decent.
