Introduction

Design Patterns

Design Patterns are reusable solutions to commonly occurring problems in software design. They provide a proven template for solving specific design challenges, making code more modular, flexible, and easier to understand. Design patterns are not specific pieces of code but rather general concepts that can be adapted to various situations.

This section of the guide provides an introduction to the most well-known creational, structural, and behavioral design patterns.

Creational

Creational design patterns deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. The basic form of object creation could result in design problems or added complexity. Creational design patterns solve this problem by somehow controlling this object creation.

Structural

Structural design patterns are concerned with how classes and objects are composed to form larger structures. They simplify the design by identifying relationships between the entities.

Behavioral

Behavioral design patterns are concerned with the assignment of responsibilities between objects and how they communicate. They focus on improving the flexibility and control of object interactions.

By understanding and applying these design patterns, developers can create more robust, maintainable, and scalable software systems.
