In this article, we’ll take a deep dive into design pattern, exploring its types and use cases.

Creational design pattern ​

Creation Design Pattern focuses on the process of object creation, ensuring that objects are created in a manner suitable to our project requirements. It helps abstract the instantiation logic from the client code.

• Singleton: Ensures a class has only one instance and provides a global point of access to it.

Structural design pattern ​

Structural Design Patterns focus on how objects and classes are arranged or composed.

• Adapter: Converts one interface into another expected by clients, enabling incompatible interfaces to work together.
• Bridge: Separates an abstraction from its implementation, allowing both to vary independently.
• Facade: Provides a unified interface to a set of interfaces in a subsystem, making it easier to use and interact with.

Behavioral design pattern ​

Behavioral Design Pattern (objects behavior) focus on how objects interact and collaborate to fulfill their responsibilities. They define patterns for managing algorithms, relationships, and responsibilities between objects.
