Flexible Grammar Definition: ○ The Interpreter Pattern is ideal for scenarios where the grammar is complex?

Short answer: And subject to change. By defining expressions as objects, it’s easy to extend or modify the grammar without affecting other parts of the system.

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.
