In this chapter, we explored Backbone's Router class. You learned how Backbone simulates pages by creating routes on a Router class and how Routers can operate using either hash-based or pushState-based routing. You also learned about the three different ways to add routes (via a routes option, a routes property, or the route method) and the three types of routes (simple, route strings, and regular expressions). Finally, you saw how to handle missing routes, respond to routing events, use multiple Routers, and most importantly how to combine a page view with composable sub-Views to power your routing methods.

In the next chapter, we'll take a look at some more advanced uses of Backbone, such as using methods in place of Backbone properties, such as model, or mixing sets of methods into multiple classes.
