This video is part of the Angular Core Deep Dive Course - https://angular-university.io/course/angular-course
In this video, we are going to learn how to use the Angular Async Pipe. We are going to learn why the async way is the best way of passing Observable data to the view, as it avoids the use of manual subscriptions and takes care of unsubscriptions automatically at component destruction time.
The Async Pipe also avoids the use of mutable data variables at the level of our components, making them more declarative. We are going to see how this pipe can be combined with the ngIf as syntax to make our templates more readable.
