11	11	JavaScript: Taking Off the Training Wheels	JavaScript is the third pillar of front-end web development. Of those pillars, it is both the most powerful and the most complex, so it’s understandable that when 24 ways asked, “What one thing do you wish you had more time to learn about?”, a number of you answered “JavaScript!” This article aims to help you feel happy writing JavaScript, and maybe even without libraries like jQuery. I can’t comprehensively explain JavaScript itself without writing a book, but I hope this serves as a springboard from which you can jump to other great resources. Why learn JavaScript? So what’s in it for you? Why take the next step and learn the fundamentals? Confidence with jQuery If nothing else, learning JavaScript will improve your jQuery code; you’ll be comfortable writing jQuery from scratch and feel happy bending others’ code to your own purposes. Writing efficient, fast and bug-free jQuery is also made much easier when you have a good appreciation of JavaScript, because you can look at what jQuery is really doing. Understanding how JavaScript works lets you write better jQuery because you know what it’s doing behind the scenes. When you need to leave the beaten track, you can do so with confidence. In fact, you could say that jQuery’s ultimate goal is not to exist: it was invented at a time when web APIs were very inconsistent and hard to work with.
