Design patterns are reusable solutions to common problems in software design. They provide a template for solving issues that arise repeatedly during development, helping developers create more efficient and maintainable code. Here are some key design patterns and their applications:
Common Design Patterns 📚
Singleton Pattern
Ensures a class has only one instance and provides a global point of access to it.Factory Pattern
Defines an interface for creating objects, letting subclasses alter the type of objects it creates.Observer Pattern
Allows an object to notify other objects about changes in its state without specifying their classes.Strategy Pattern
Enables an algorithm to be selected at runtime.
When to Use Design Patterns 🔍
- Reusability: Avoid code duplication by using proven solutions.
- Maintainability: Simplify code structure for easier updates and debugging.
- Scalability: Design systems that can adapt to future changes.
