Design patterns are general repeatable solutions to common problems encountered in software design. They represent best practices and provide a way to structure and organize code to solve certain types of problems. Design patterns can speed up the development process by providing tested, proven development paradigms.

Key characteristics of design patterns include:

  1. Reusability: Design patterns are reusable solutions to common problems. They provide a template for solving particular issues in a consistent and efficient way.
  2. Flexibility: Design patterns are adaptable and can be customized to fit the needs of a specific application. They allow for variations in the structure and behavior of software systems.
  3. Abstraction: Design patterns abstract the complexities of a problem by providing a high-level framework. They allow developers to focus on solving the specific details of a problem without getting bogged down in unnecessary implementation details.
  4. Scalability: Design patterns are scalable and can be applied at different scales, from small classes to entire architectures. They provide a way to manage the complexity of larger systems.
  5. Common Vocabulary: Design patterns provide a common vocabulary and understanding among developers. When a design problem is discussed, referring to a well-known pattern can help convey the solution more effectively.

Design patterns can be categorized into three main groups:

  1. Creational Patterns

2. Structural Patterns

3. Behavioral Patterns
