What is prototypal inheritance in JavaScript?

Prototypal inheritance is a feature in JavaScript where objects can inherit properties and methods from other objects.

How does it differ from classical inheritance?

In classical inheritance, classes inherit from other classes, while in prototypal inheritance, objects inherit directly from other objects.

Can you give me an example of how to implement it?

Sure! You can create an object and set its prototype to another object using Object.create(). Here's a simple example:

const parent = { greet() { console.log('Hello!'); } };
const child = Object.create(parent);
child.greet(); // Outputs: Hello!

What are the advantages of using prototypal inheritance?

Some advantages include more flexible object creation, easier to share methods, and reduced memory usage since methods are shared.
