Design Patterns

Design patterns are reusable solutions to common software engineering problems. They are a way of abstracting code for reuse across multiple projects, and provide a way of organizing code for easy maintenance. Design patterns can be divided into three main categories: structural patterns, behavioral patterns and creational patterns. Examples of design patterns include the Singleton pattern, the Factory pattern, the Observer pattern, the Builder pattern, the Prototype pattern, the Adapter pattern, the Facade pattern and the Proxy pattern. By using design patterns, developers can improve the readability and maintainability of their code, as well as improving overall code quality and better code reuse.
