 We define the component by extending `sap/ui/core/UIComponent` and supplement the component with additional metadata. Within the `interfaces` settings, we specify that the component should implement the `sap/ui/core/IAsyncContentCreation` interface. This allows the component to be generated asynchronously, which in turn sets the component's rootView and router configuration to async.
 
-When the component is instantiated, OpenUI5 automatically calls the `init` function of the component. It's obligatory to make the super call to the `init` function of the base class in the overridden `init` method. In this section, we also instantiate our data model and the `i18n` model, similar to what we did earlier in the `onInit` function of our app controller.

 Finally we call the `createContent` hook method of the component. This method creates the content \(UI Control Tree\) of this component. Here, we create the view as we did in the `index.?s` file to set our app view as the root view of the component.
