Design patterns·Making things
somebody says a pattern is 'GoF' and means it came from the 1994 book rather than from a framework.
Gang of Four
Also calledGoF, Design Patterns book, the four authors
The four authors of Design Patterns (1994) and, by extension, the twenty-three patterns catalogued in it, split into creational, structural and behavioural. Several of them are now language features rather than patterns — iterator, and in functional-first languages strategy and command — and a few are almost never written deliberately. It is still the shared reference point that lets an interviewer say 'a structural pattern' and be understood.
