const user = { name: "John" }; greet.call(user, "Hi"); greet.apply(user, ["Hello"]); const bound = greet.bind(user, "Hey"); bound();

Real-world example (ShopNest)

ShopNest’s browser cart uses modern JavaScript: fetch APIs with async/await, modules, and clear error handling.

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.
