In this chapter, we learned about different objects that Marionette provides to manage views, such as the
BabySitter objects. This management is definitely needed, but it takes a lot of glue code to achieve it. So having it out of the way at the time of building an application is a very good reason to start using these objects.
In the next chapter, we will learn how to modularize our applications into small modules of subapplications in order to keep different functionalities of our website separated from each other, but still working together.
