High Performance JavaScript
Ever wonder why the page appears frozen or why you get a dialog saying, "this script is taking too long"? Inside of the browser, JavaScript and the page's UI are very intertwined, which means they can affect each other and, in turn, affect overall page performance. Ensuring the fastest execution time of JavaScript code isn't about geek cred, it's about ensuring that the user experience is as fast and responsive as possible. In a world where an extra second can cost you a visitor, sluggishness due to poor JavaScript code is a big problem. In this talk, you'll learn what's going on inside the browser that can slow JavaScript down and how that can end up creating a "slow page". You'll also learn how to overcome the conspiracy against your code by eliminating performance bottlenecks.
