This is Part 2 of a series of tutorials. You can find Part 1 here. We’re good with Backbone.Model. We’re good with Backbone.Collection. We’re good with Backbone.Events. So: Backbone.Controller: If you’re coming from Rails land, you’ll be pretty familiar with this guy, although it’s got a pretty neat twist. You get to write your routes right in the controller. This is very, very nice to work with.
