What is prototype inheritance?
Short answer: In JavaScript, every object can inherit properties from another object called its prototype. This enables object reusability. Example: const animal = { eats: true };
Example code
const dog = Object.create(animal); Follow me on LinkedIn: dog.barks = true; console.log(dog.eats); // true (inherited)
Real-world example (ShopNest)
Prefer arrow functions for React/event callbacks in ShopNest so this is not accidentally rebound.
Say this in the interview
- Define — one clear sentence (the short answer above).
- Example — relate it to a project like ShopNest or your real work.
- Trade-off — when you would not use it.
