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.

Good Video sir. i think the counterObservable.subscribe() method returns object of type subscription rather than Observable.

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.

after creating 3 subscribers, when we click unsubscribe will it unsubscribe all observables?

[@icursealot]

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.

[@JuanHeribertoPoquiomaEsquivel]

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); })

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