ReplaySubject | ReplaySubject vs BehaviorSubject | RxJS ReplaySubject - Angular (Tutorial 34)

ReplaySubject is one of the variant of Subject and it can emit old values to new subscribers. It can buffer the old emitted values and then immediately pass those values to the new subscribers and the latest value to the existing subscriber
There are 3 variants of Subject:
1) BehaviorSubject
2) ReplaySubject
3) AsyncSubject
Unlike BehaviorSubject ReplaySubject don't have any initial value, so if your requirement says that initial values is not needed but instead want to emit multiple previous emitted values(that can be decide how many old values) to emit to new subscribers so that they have some data use Replay Subject.

It's really hard to make things easier to made understand in such a simple way. We are eagerly waiting that you would create a rxjs series with Angular with some real use case as you do always.

Hi Nisha Singla, The way you explain is best and self explanatory at once. Also you explain with coding examples that makes your video different from all others. You must start your Udemy course. Good work keep it up. Kudos !!
