Form Inputs:?

Short answer: In web applications or forms, the Memento Pattern can be used to save the state of form inputs at various stages. This allows users to undo their changes or restore the form to a previous valid state.

Real-world example (ShopNest)

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.
