What are the different types of Subjects available in Angular?
  • A subject is a special type of Observable which shares a single execution path among the observers which results in a multicast (one to many).
  • There are four types of Subjects available based on how they behave:
  1. Subject - No initial value or replay available
  2. AsyncSubject - Emits latest values to subscribers on completion of the async task
  3. BehaviouralSubject - requires an initial value and emits current values to new subscribers
  4. ReplaySubject - replays a specified number of last values to new subscribers
