Patterns Overview

🐶 Common Design Patterns

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

  

• Factory Pattern
  Defines an interface for creating objects, letting subclasses decide which class to instantiate.

  

• Observer Pattern
  Establishes a one-to-many dependency between objects, notifying them of state changes.

  

🛠️ Practical Applications

• Use Singleton for managing global resources like database connections.
• Apply Factory in scenarios requiring flexible object creation (e.g., plugins).
• Implement Observer for event-driven systems (e.g., UI updates, logging).
