I am off to Dallas this morning to give an all-new version of the Refactoring JavaScript talk. This year, we will be looking at testing and refactoring jQuery plugins, using Screw.Unit, Smoke, and blue-ridge.
You can grab the slides here, but as usual the slides tell only a little of the story. Instead, grab the project itself, and use git’s local history to start at the beginning and watch the refactorings step-by-step.
