Answer
The Observer Pattern allows a subject to notify multiple observers of events without knowing who they are.
The Observer Pattern lets a subject (like a product availability service) send updates to many observers (like email, SMS, and app notifications) whenever a product is back in stock. Each observer registers with the subject and gets notified of changes automatically, keeping the notification logic separate from the main application flow.
