The same save method is used for both add and edit since `HeroService` will know when to call `post` vs `put` based on the state of the `Hero` object. The same save method is used for both add and edit since `HeroService` will know when to call `post` vs `put` based on the state of the `Hero` object.
Earlier we used the `save()` method to return a promise, so when the promise resolves, we call `emit` to notify `HeroesComponent` that we just added or modified a hero. `HeroesComponent` is listening for this notification and will automatically refresh the list of heroes to include our recent updates. After we save a hero, we redirect the browser back to the to the previous page using the `goBack()` method.
