good explanation, i think it was a nice opportunity to explain what it is a hot and cold observable, a cold observable is like 1 to 1 relationships, like netflix service with an specific user, hot observable is like a cinema, 1 to many relationship, the data producer is created before the data is emited, so all the subscribers recibe the same data

Thanks, Leela another posibility to unsubscribe is to create an array of Subcription type, and on Destroy life cycle hook unsubscribe all elements inside the array

Hi leela, why the count value is logging in VS code terminal instead of browser console.

[thasiaanjani]

means that if eachcomponent has ngOnInit that call some api, i can cancelled/unsubscribe thatcall when i open another menu. so i no need to wait the api from old component and i can call the api immediately

as you told observables leak memory so why don't we use .then rather than .subscribe
