What are the different data types in JavaScript?

Short answer: Primitive types: string, number, boolean, null, undefined, symbol, bigint Reference types: object, array, function

Example code

let name = "Sandeep"; let obj = { age: 30 };

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.
