The Gang of Four (Design Patterns)

The Gang of Four refers to four authors—Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides—who wrote a foundational book on design patterns in software development. These patterns are proven solutions to common programming problems, aiding developers in creating flexible, maintainable, and efficient code. Think of them like best practices or blueprints that help organize complex systems, making software easier to understand and adapt over time. Instead of reinventing the wheel for each new project, developers can apply these standard patterns to solve recurring challenges effectively.
