What is the async pipe in Angular?

The async pipe in Angular is a built-in pipe that allows you to subscribe to an Observable or Promise directly in your template.

How does it help with managing subscriptions?

It automatically handles subscriptions for you, meaning you don't have to manually subscribe and unsubscribe, reducing memory leaks.

Can you give me an example of how to use it?

Sure! You can use it like this: <div *ngIf="data$ | async as data">{{ data }}</div> where data$ is an Observable.

What happens if the Observable emits new values?

The async pipe will automatically update the view with the latest emitted value whenever the Observable emits a new value.
