Object.create is new to JavaScript (it's part of ES5), but NodeJS supports it so we can safely use it. This creates a new object that inherits from another object.

JavaScript - Classical OOP vs. Prototypal OOp.js

// --- Classical OOP
function Person(name) {
  this.name = name
}
Person.prototype = {
  greet: function () {
    return "Hello world, my name is " + this.name;
  }
};

var frank = new Person("Frank Dijon");
frank.greet();

// --- Prototypal OOP
var Person = {
  greet: function () {
    return "Hello world, my name is " + this.name;
  }
};
var frank = Object.create(Person);
frank.name = "Frank Dijon";
frank.greet();
