Benchmark: ES6 Class vs Prototype vs Object Literal vs ES6 Class Extends

Script Preparation code:

class ClassPoint {
    constructor(x, y) {
        this.x = x;
        this.y = y;
    }

    add(point) {
        this.x = this.x + point.x
        this.y = this.y + point.y
    }

    sub(point) {
        this.x = this.x - point.x
        this.y = this.y - point.y
    }
}
function FunctionPoint(x, y){
	this.x = x;
	this.y = y;
}

FunctionPoint.prototype.add = function(point){
		this.x = this.x + point.x
        this.y = this.y + point.y
}

FunctionPoint.prototype.sub = function(point){
		this.x = this.x - point.x
        this.y = this.y - point.y
}

function ObjectPoint(x, y){
	return {
      	x, 
      	y, 
      	add:(point) => {
          this.x = this.x + point.x
          this.y = this.y + point.y
    	},
      	sub:(point) => {
          this.x = this.x - point.x
          this.y = this.y - point.y
    	},
    }  
}
class Base {
	constructor(x, y){
		this.x = x;
		this.y = y;
    }
}
class ClassPoint2 extends Base {
  
	add(point){
		this.x = this.x + point.x
        this.y = this.y + point.y
    }

	sub(point){
		this.x = this.x - point.x
        this.y = this.y - point.y
    }
}

Tests:

ES6 Class
var p1 = new ClassPoint(10, 10); var p2 = new ClassPoint(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Function Prototype
var p1 = new FunctionPoint(10, 10); var p2 = new FunctionPoint(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Object Literal
var p1 = ObjectPoint(10, 10); var p2 = ObjectPoint(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
Class extends
var p1 = new ClassPoint2(10, 10); var p2 = new ClassPoint2(10, -10); var sum = p1.add(p2); var dif = p1.sub(p2);
