How do I implement prototypal inheritance in JavaScript?

Prototypal inheritance allows objects to inherit properties and methods from other objects. You can implement it using the Object.create() method.

Can you give me an example of how to use Object.create()?

Sure! Here's a simple example:

const animal = { eats: true };
const rabbit = Object.create(animal);
rabbit.hops = true;
console.log(rabbit.eats); // true

What if I want to add methods to the prototype?

You can add methods directly to the prototype object. For example:

const animal = {
  eats: true,
  speak() { console.log('Animal speaks'); }
};
const rabbit = Object.create(animal);
rabbit.hops = true;
rabbit.speak(); // Animal speaks

Is there a way to check if an object inherits from another?

Yes! You can use the instanceof operator or the isPrototypeOf() method to check inheritance.
