Observer Pattern Explained in 1 Minute | Quick System Design Guide | Design Principles
The Observer Pattern is a behavioral design pattern that allows one object, known as the **subject**, to notify multiple dependent objects, called **observers**, about changes in its state. When the subject changes, all registered observers are automatically updated. This pattern promotes loose coupling between components, making it easier to manage and extend systems. It’s commonly used in event-driven systems and user interfaces to keep various parts of an application in sync without tight dependencies.
