A design pattern goes to the supermarket
summary
Uses supermarket scenes and simple code snippets with drawings to map concrete behaviors to design patterns: a grocery note encapsulates a request as the command pattern, a sign-up email list for restock is the observer pattern, a smartphone translator bridges Spanish labels with an adapter, different bakeries implement a factory method to create breads, a sandwich workflow becomes a template method, and putting away groceries acts as a facade. Claims patterns are conceptual blueprints not copy‑paste code and shows practical, working analogies.
