🧩 What Are Design Patterns?
Design patterns are reusable solutions to common problems in software design. They provide a template for addressing issues that arise repeatedly during development, helping developers create efficient, maintainable, and scalable code.
Whether you're building applications or exploring system architecture, understanding design patterns is essential. They act as a bridge between good object-oriented design and practical implementation.
📚 Types of Design Patterns
Design patterns are typically categorized into three groups:
🛠️ Creational Patterns
- Singleton: Ensures a class has only one instance.
- Factory Method: Defines an interface for creating objects.
- Abstract Factory: Provides an interface for creating families of related objects.
🧱 Structural Patterns
- Adapter: Matches interfaces of different classes.
- Decorator: Adds responsibilities to objects dynamically.
- Composite: Composes objects into tree structures.
🧠 Behavioral Patterns
- Observer: Enables automatic notification of changes.
- Strategy: Defines a family of algorithms.
- Command: Encapsulates requests as objects.
