views require heroic data.Currently, the AppComponent analog data is displayed. There are at least two places to improve: First, defining a hero's data should not be a component's task; second, it is not so easy to share the data of this heroic list with other components and views.We can refactor the task of acquiring heroic data into a single service that will provide heroic data and share the service among all the components that need the hero's data.Create Heroserviceappcreate a file named u
