Can I extend multiple classes in JavaScript?

In JavaScript, you cannot directly extend multiple classes like in some other languages. However, you can use mixins or composition to achieve similar functionality.

What are mixins and how do they work?

Mixins are a way to add properties and methods from one class to another without using inheritance. You can create a mixin and then apply it to multiple classes.

Can you show me an example of using mixins?

Sure! Here's a simple example:

const canFly = {
  fly() {
    console.log('Flying!');
  }
};

class Bird {
  chirp() {
    console.log('Chirp!');
  }
}

Object.assign(Bird.prototype, canFly);

const sparrow = new Bird();
sparrow.chirp(); // Chirp!
sparrow.fly(); // Flying!
