Accepted Answer

Magento patterns are design patterns used in Magento development to solve common problems and improve code reusability.

Singleton Pattern: Ensures a class has only one instance and provides a global point of access to it.
Factory Pattern: Used to create objects without specifying the exact class of object that will be created.
Observer Pattern: Allows objects to subscribe and unsubscribe to events and be notified when those events occur.
Decorator Pattern: Allows behavior to be added to an object dynamically.
Repository Pattern: Used to separate the logic that retrieves the data from the database from the business logic.
Service Layer Pattern: Provides a way to encapsulate application logic and expose it as a service to be consumed by other parts of the application.
