Learning Design Patterns

Welcome to my repository for exploring and mastering Design Patterns! This space serves as a comprehensive resource to document my learning, insights, and implementation of various design patterns in software development.

🌟 About This Repository

This repository is dedicated to:

• Understanding Design Patterns through theoretical concepts and practical examples.
• Documenting the Gang of Four (GoF) design patterns and their use cases.
• Implementing patterns in [your chosen programming language].
• Sharing resources, references, and best practices for efficient software design.

📚 Design Patterns Overview

Design Patterns are categorized into three main types:

1. Creational Patterns: Focus on object creation mechanisms.

   • Factory Method
   • Abstract Factory
   • Builder
   • Prototype
   • Singleton

2. Structural Patterns: Deal with the composition of classes and objects.

   • Adapter
   • Bridge
   • Composite
   • Decorator
   • Facade
   • Flyweight
   • Proxy

3. Behavioral Patterns: Concerned with object interaction and responsibilities.

   • Chain of Responsibility
   • Command
   • Interpreter
   • Iterator
   • Mediator
   • Memento
   • Observer
   • State
   • Strategy
   • Template Method
   • Visitor
