How does inheritance work in JavaScript?
Short answer: Objects inherit from other objects via Object.create(), constructor functions, or classes (ES6). Methods can be shared via prototypes. Example using constructor: function Person(name) { this.name = name; } Person.prototype.greet = function() { console.log(`Hello ${this.name}`); }; const p = new Person("Sandeep"); p.greet(); // Hello Sandeep
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
- 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.
