"just do it" JavaScript (or any programming language for that matter) cannot be learned by just reading. One must actually write with the language to get used to the language, as well as gain muscle memory for the syntax. Do something, even something very simple, like a console-based game (which is essentially just a state machine), or create your own pub-sub library (which deals alot with object and array manipulation), or recreate some data structure (binary tree, linked lists, rings, etc.). These simple exercises can go a long way. These books help as well. - JavaScript: The Definitive Guide - High Performance JavaScript
