With the observer pattern, we can subscribe certain objects, the observers, to another object, called the observable. Whenever an event occurs, the observable notifies all its observers!

When to Use

Use this when you need to notify multiple parts of an application about state changes or events

This is helpful for implementing event-driven, asynchronous communication between components
