Benchmark: ES6 Class vs Prototype vs Object Literal vs Functional v2

Script Preparation code:

class Point {
    constructor(x, y) {
        this.x = x;
        this.y = y;
    }

    add(point) {
        return new Point(this.x + point.x, this.y + point.y);
    }

    sub(point) {
        return new Point(this.x - point.x, this.y - point.y);
    }
}
var Point1 = Point;

function Point2(x, y) {
    this.x = x;
    this.y = y;
}
Point2.prototype.add = function(point) {
    return new Point2(this.x + point.x, this.y + point.y);
}

Point2.prototype.sub = function(point) {
    return new Point2(this.x - point.x, this.y - point.y);
}

function Point3(x, y) {
    return {
        x,
        y,
        add: (point) => Point3(this.x + point.x, this.y + point.y),
        sub: (point) => Point3(this.x - point.x, this.y - point.y)
    }
}

var add = (a, b) => (a.x + b.x, a.y + b.y)
var sub = (a, b) => (a.x - b.x, a.y - b.y)

Tests:

ES6 Class
var p1 = new Point1(10, 10); var p2 = new Point1(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Function Prototype
var p1 = new Point2(10, 10); var p2 = new Point2(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Object Literal
var p1 = Point3(10, 10); var p2 = Point3(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Functional
var p1 = {x:10, y:10}; var p2 = {x:10, y:-10}; var sum = add(p1, p2); var dif = sub(p1, p2);
