How does BehaviorSubject differ from Subject in state management

Question

With the help of code can you tell me How does BehaviorSubject differ from Subject in state management?

Answer 1

Feature	Subject	BehaviorSubject
Initial Value	No initial value	Requires an initial value
Last Emitted Value	Does not store the last emitted value	Always stores the last emitted value
New Subscriber Behavior	New subscribers do not receive past values	New subscribers immediately receive the last emitted value
Use Case	Useful for event-based streams where history is not required	Useful for state management where retaining the last value is important
State Management	Not ideal for storing state as it doesn't persist values	Ideal for state management as it keeps the latest state
Example	const subject = new Subject<number>();	const behaviorSubject = new BehaviorSubject<number>(0);
