Unsubscribe to an Observable | Observables | Angular 12+

In this lecture you will learn, how to unsubscribe to an observable. We have learned that an observable emits some data. Now, there are some observables which emits data indefinitely. For suct kind of observables, we need to unsubscribe to them explicitely.
If we dont unsubscribe to these observables, then they will keep on emitting the data indefinitely and at some point of time our memory will run out of space. So, in this lecture, lets learn how you can unsubscribe to an Observable.

    Amazing tutorial. You said we need to unsubscribe observable otherwise we will run out of memory. But here we are not storing data emitted, then how would we run out of memory.

    So, is there the way to stop all these intervals with unsibscribing somehow from all subs or we only can create one observable and unsubscribe only from that observable?

    You need to unsubscribe from the observable in each component, if you are using it in multiple components. If you have subscribed to an observable at multiple places in a single component, you need to unsubscribe from it only once, when the component is destroyed.

    You have created unsubscribe and subscribe methods with same name unsubscribe and subscribe can we give names as our own?

    I have tried it but its only closing one of the subscribers even if you click to unsubscribe all the time it does not stop.

    it only stops the last one because it has the reference to the observable... the others have lost the reference (leak memory) this line > this.counterSub = this.counterObservable.subscribe((val) => { console.log(val); })
