The Gang of Four (GoF)

The Gang of Four (GoF) refers to four software designers—Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides—who authored a seminal book in 1994 on reusable object-oriented design patterns. These patterns are proven solutions to common programming challenges, helping developers write flexible, maintainable code. The GoF's work has significantly influenced software engineering, providing a common language for design solutions and improving the quality and consistency of software development across various projects.
