What is the difference between parameters and arguments?

Short answer: Parameters: variables listed in the function definition Arguments: actual values passed to the function when calling it Example: function greet(name) { // name = parameter console.log(`Hello ${name}`); }

Example code

greet("Sandeep"); // "Sandeep" = argument

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.
