Javascript Programming Tutorials, Guides & Best Practices

Mixins are a way to add behavior to objects or classes without using inheritance. They allow you to compose multiple behaviors in a single object or class.

const canEat = {
    eat() {
        console.log(`${this.name} is eating.`);
    }
};

const canWalk = {
    walk() {
        console.log(`${this.name} is walking.`);
    }
};

class Person {
    constructor(name) {
        this.name = name;
    }
}

Object.assign(Person.prototype, canEat, canWalk);

const person = new Person('John');
person.eat(); // Output: John is eating.
person.walk(); // Output: John is walking.
