Programming Language Parsers:?

Short answer: The Interpreter Pattern is commonly used in building parsers for domain-specific languages (DSLs) or simple programming languages. Each statement or expression in the language can be represented as an object, and the interpreter evaluates these statements to execute the program.

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.
