THIS is what they think that you need in order to "Master" JavaScript?!? These are all beginner steps! There is no mention of Prototypical inheritance (upon which the language itself is built).

This post is trivial, surface-level information, and has as much to do with "Mastering" Javascript as training wheels do to riding a motorcycle.
