Iterating Over a List of Products:?

Short answer: The Iterator Pattern is commonly used when working with product lists, customer lists, or any other collection where you need to iterate over items sequentially. For instance, in an e-commerce application, you might use an iterator to list products, iterate through available categories, or paginate results.

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.
