The Everyday Backend Engineer: Step 10 — The Observer Pattern

1. 1Identify objects that need to notify other objects of changes using the Observer pattern
2. 2Implement the Subject interface to define the contract for objects being observed
3. 3Create Observer interfaces to define the contract for objects doing the observing
4. 4Register and unregister observers as needed to manage dependencies
5. 5Test the Observer pattern implementation to ensure loose coupling and correct notifications

Backend engineers and software developers can benefit from this pattern to write more scalable and flexible code

💡 The Observer pattern helps decouple objects, making it easier to modify and extend backend systems
