Up till now the best video on Subjects and BehavioralSubject I have watch so far. One good thing is that you explained by giving an example of services and why subjects should be used in place of it. Please keep up the good work.

Nice video! The most important thing to get from it is that a BehaviorSubject holds one value regardless of when it was added (with next() or initializing ). When it is subscribed it emits the value immediately. A Subject doesn't hold a value, the value has to be set after something is subscribed to it.

The best explanation that i heard so far about behaviorSubject/Subject. You just earned another subscriber (not the observable hahaha)

Hi Oleksandr!
What do you think could be the consequences of Signals on NgRx?
Many thanks!

yeah but with behavioral subject if i dont put initial value the 3 component i try to show the value break i think

[SrinathJog]

Thanks for this clear understandable video. My question is, Can we use Behavior Subject instead of Subject everywhere ? I mean do we need to replace subject with Behavior Subject completely because Behavior Subject has initial value and we can have value of it anytime unlike subject.
Or we have some unique scenarios that we have to use simply Subject in place of Behavior Subject ? What is the significance of both.

Thanks in advance

I love to use BehaviorSubject for all variables used in templates!

[CodingAbroad]

It makes you think why Subject exists in the first place. I’ve never found a need for it

[MrJeszam]

I agree. Subject or plain subject is stupid and useless.
