A BehaviorSubject can remember the latest value emitted, but what if we wanted Observer B to see all the previous values emitted in the past? We can't do that with BehaviorSubject, but there is ReplaySubject, which allows us to do that. This lessons teaches you everything you need to know about ReplaySubjects.

I think one important thing to note is that by default ReplaySubject without arguments replays the complete stream.
