GoF (Gang of Four)

The Gang of Four (GoF) refers to four authors—Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides—who wrote the influential book "Design Patterns: Elements of Reusable Object-Oriented Software" in 1994. They identified 23 common solutions to recurring design problems in software development, known as design patterns. These patterns provide tried-and-true templates for structuring code, promoting code reuse, flexibility, and maintainability. In essence, GoF is a foundational guide that helps developers design software more effectively by using established, peer-reviewed strategies.
