Also compares State vs Strategy pattern, discusses combining with Observer and Command patterns, and weighs benefits (eliminates conditionals, OCP/SRP compliance, testability) against drawbacks (class proliferation, tight coupling between states). ## Full article daily.dev links to this article rather than hosting it.
