Maybe you've inherited some smelly code, or maybe you've written some yourself, rushing to get a feature out the door knowing that you're leaving yourself a mess to clean up later. No matter how you end up with smelly code, eliminating smells is an important step toward making code easier to work with -- for you and your fellow developers -- reducing opportunities for introducing bugs, and making your code easier to test. Heck, it can even help you get a new job. In this talk, we'll look at some common code smells and how to address them; along the way, we'll take a peek at templates, deferreds, promises, and other techniques that can help you tidy up your JavaScript.
