The book (1994), often called the "Gang of Four" (GoF) book, is a landmark text in software engineering. Written by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, it provides a catalog of 23 design patterns that solve common, recurring problems in software design. Why it is Considered a "Good Story" (Masterpiece)
: While authoritative, some modern reviewers find it dense. Beginners often recommend starting with Head First Design Patterns on Quora as a more approachable introduction before diving into the GoF original.
