In Angular, we want to keep our controllers lightweight and specific to the view that it is controlling. To accomplish this, we are going to refactor our categories collection into a CategoriesModel. A recurring theme in Angular 2 is that everything is "just a class". When we create our controllers and services in an Angular 2 style, they are also "just a class". We will see this in action as we convert our controller almost verbatim into a service.

Hi, what is the advantage of CategoriesModel being a service of CommonModule instead of CategoriesModule?

Hi Stanislav -- I like to break out services that are used by multiple components into a common module so that I can spin up one component without having a hard dependency on another component.
