 Dagger 2 provides `@Scope` as a mechanism to handle scoping. Scoping allows you to keep an object instance for the duration of your scope.
 
+## Default scopes

 In the previous tutorial, we looked at _two_ scopes, namely `@Singleton` and `@Reusable`. Singleton does what its name suggests, and "caches" the dependency instance for the lifecycle of the `@Component`, and Reusable tells Dagger that while we'd prefer that a cached instance be used, we're fine if Dagger needs to create another one. The new Dagger 2 [user guide](https://dagger.dev/users-guide) does a pretty good job differentiating between Singleton, Reusable and unscoped dependencies which I'll reproduce here.

 I'll do a small demo to show the difference between unscoped and singleton dependencies, then we'll move on to defining our own scopes.

 Like Arun mentioned in the [additional notes](/posts/dagger-the-easy-way-part-1/#setting-up-the-object-graph) for the previous article, ensuring a singleton Component stays that way is the user's job. If you initialize the component again within the same scope, you'll get a new set of dependencies. That is part of why we store our component in the [Application](https://developer.android.com/reference/android/app/Application.html) class, because it is the singleton for our apps.
