Short answer: In game development, game objects like enemies, obstacles, and power-ups can be stored in collections. The Iterator Pattern can be used to iterate over these objects, processing each object individually without exposing the underlying collection implementation. Improvements and Considerations:

Real-world example (ShopNest)

Use a GoF pattern in ShopNest only when it removes duplication or makes a change safer—explain the problem it solves in the interview.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
