Hierarchical Injection in Angular | Services & Dependency Injection | Angular 12+
In this lecture, you will learn what is heirarchical dependency injection in Angular and how it works? In Angular, angular uses hierarchical dependency injection. That means, when we ask Angular to inject a dependency for a component, the same instance of that dependency get's injected for the child components and their child components as well.
Let's understand hierarchical dependency injection with some examples and how heirarchical dependency can be injected in varius places of an Angular App.

Another very good explanation from you.

Hello Manoj Sir, Regarding Hierarchial DI, now angular is saying to use "providedIn" option with three possible values 'root' | 'platform' | 'any'. Can you please make a video on this option for Angular ? No compulsion. Just a request. Thanks.

Why are we able to use this service inside any component by just importing it and creating its instance without declaring this "providers" array inside the same or parent component/module?
