Answer
The publisher–subscriber model allows components to react to changes without tight coupling.
Publishers broadcast notifications without knowing subscribers, improving modularity and scalability.
Quick Answer
In the pub-sub model, publishers raise events without knowing who is listening. Subscribers register and react independently. This removes direct dependencies between components — you can add or remove subscribers without changing the publisher. Great for UI events, domain events, and plugin systems.
