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

Had a blast watching this! I used ngneat until destroy in my project and I wanted to grasp the concept of unsubscribing your observables better. Liked and subbed!

[@mugatu2017]

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

Great

[@thasiaanjani1461]

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

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

[@LeelaWebDev]

[@vaibhavsharma2578]

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

[@ragulprime7159]

[@Rm_rm_bjp]

plz provide interview types of qustions bro

[@LeelaWebDev]

Yeah will do

[@mihaicojusnean]

Why I understand what his saying?

[@ChessNetwork16]

You are only programming which is very tough to understand for a beginner. Plz clear concept of Observable

[@LeelaWebDev]

At the end you need to understand how it works in the code programmatically. If you practice more you will get new doubts. That is the reason i am showing through code.

[@madhavikesana5636]

Yes @leela web dev show like this only through coding.
