Welcome to the design patterns guide! This resource explores common software design patterns that solve recurring problems in application development. Whether you're a beginner or an experienced developer, understanding these patterns will improve your code quality and maintainability.

📌 What Are Design Patterns?

Design patterns are reusable solutions to problems arising in specific contexts. They provide a template for solving issues that can be applied in different situations.

🧩 Popular Design Patterns

  1. Singleton

    • Ensures a class has only one instance and provides a global access point to it.
    • Use case: Managing database connections or configuration settings.
    Singleton Pattern

  2. Factory Method

    • Defines an interface for creating objects but lets subclasses alter the class of objects it creates.
    • Use case: Decoupling object creation from usage.

  3. Observer

    • Enables a subscriber pattern where an object (subject) notifies other objects (observers) of changes.
    • Use case: Implementing event systems or real-time updates.
    Observer Pattern

  4. Strategy

    • Encapsulates algorithms as objects, allowing them to be interchangeable.
    • Use case: Dynamic behavior switching (e.g., payment methods).
    Strategy Pattern

🚀 Why Use Design Patterns?

  • Reusability: Avoid reinventing the wheel by leveraging proven solutions.
  • Maintainability: Simplify code structure and reduce complexity.
  • Collaboration: Use a shared vocabulary for developers.
