How do I create a mixin in JavaScript?

Can you explain what a mixin is in JavaScript?

Sure! A mixin is a design pattern that allows you to add properties and methods from one object to another, enabling code reuse.

How do I create a mixin in JavaScript?

You can create a mixin by defining a function that takes an object and adds properties or methods to it. Here's a simple example:

const mixin = {
  greet() {
    console.log('Hello!');
  }
};

function applyMixin(target) {
  Object.assign(target, mixin);
}

class Person {}
applyMixin(Person.prototype);

const person = new Person();
person.greet(); // Outputs: Hello!

Can I use multiple mixins?

Yes, you can use multiple mixins by applying each one to the target object. Just call Object.assign with multiple sources.
