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 show me a simple example?

Sure! Here's a basic example:

const animal = { 
  speak() { console.log('Animal speaks'); }
};

const dog = Object.create(animal);

dog.speak(); // Output: Animal speaks

What if I want to add more properties to the dog object?

You can add properties directly to the dog object like this:

dog.breed = 'Labrador';
console.log(dog.breed); // Output: Labrador

How does this differ from classical inheritance?

In classical inheritance, you define classes and create instances. Prototypal inheritance is more flexible and allows for dynamic object creation.
