We refactor a wall of JavaScript code with Raddevon, in thisvideo. We take a function that's 5 screens high, and extract methods to uncover the underlying structure.

Today I'm going to refactor acts_as_list Rails library. It allows to treat Rails model records as part of an ordered list and offers methods like #move_to_bottom and #move_higher.
