Design patterns are reusable solutions to common problems that occur in software design and development.
They provide guidelines and best practices to solve these problems efficiently and effectively.
While the number of design patterns can vary depending on the source and categorization.
Here are some of the most commonly recognized types of design patterns:
1.Creational Patterns:
- Singleton
- Factory Method
- Abstract Factory
- Builder
- Prototype
2.Structural Patterns:
- Adapter
- Bridge
- Composite
- Decorator
- Facade
- Flyweight
- Proxy
3.Behavioral Patterns:
- Observer
- Strategy
- Command
- Iterator
- Mediator
- Memento
- State
- Template Method
- Visitor
- Chain of Responsibility
4. Architectural Patterns:
- Model-View-Controller (MVC)
- Model-View-ViewModel (MVVM)
- Layered Architecture
- Repository Pattern
- Dependency Injection
- Event-Driven Architecture (EDA)
These are just a few examples of the types of design patterns commonly used in programming. Each pattern addresses a specific problem and provides a recommended solution. It’s important to note that design patterns are not limited to these categories, and new patterns can emerge as software development practices evolve over time.
