This was posted on HN a few weeks ago...might be somewhat useful in that it does cover some more recent concepts in JS.

I recommend this iPad-book 'Let's Learn ES6' by Ryan Christiani [1] to bring you up to speed with some of the features of modern JavaScript. It's got videos on it!

Another resource that I like is Wesbos's video tutorials on all things JS. He has a separate course on ES6 which is great! And then there is MDN.

Maybe the books from Axel Rauschmayer are what you’re looking for.
