If you start to use a DB like mongo, you might be better off creating objects with mongoose but that‘s personal preference as well. As for your example -

1) Export Person

module.exports = Person;

2) Import Person from another file

const Person = require(‘../path/to/Person‘);

3) Create Person with the?

const mitch = new Person(‘Mitch‘);

You should read up on?javascript‘s prototype. Every object has a reference to?Object.prototype. Then you can create objects with?Object.create(obj)?to create objects and assign the new object‘s prototype as the reference being passed in to?

Here‘s an example from MDN

// Shape - superclass

function Shape() {

this.x = 0;

this.y = 0;

}

?

// superclass method

Shape.prototype.move = function(x, y) {

this.x += x;

this.y += y;

console.info(‘Shape moved.‘);

};

?

// Rectangle - subclass

function Rectangle() {

Shape.call(this); // call super constructor.

}

?

// subclass extends superclass

Rectangle.prototype = Object.create(Shape.prototype);

Rectangle.prototype.constructor = Rectangle;

?

var rect = new Rectangle();

?

console.log(‘Is rect an instance of Rectangle?‘,

rect instanceof Rectangle); // true

console.log(‘Is rect an instance of Shape?‘,

rect instanceof Shape); // true

rect.move(1, 1); // Outputs, ‘Shape moved.‘
