Benchmark: Closure v Prototypical Objects

Script Preparation code:

function Foo() {
   'use strict';
   let self = {};

   /****************************************************************************
    * Properties
    ***************************************************************************/
   self.foo1 = 15;
   self.foo2 = 'testing';
   self.foo3 = { i: 1, am: 2, a: 3, literal: 4 };
   self.foo4 = null;

   /****************************************************************************
    * Methods
    ***************************************************************************/
   self.constructor = function () {
      self.foo4 = self.foo2 + self.foo1;
   }

   self.doFoo1 = function () {
      return self.foo2;
   }

   self.doFoo2 = function () {
      self.foo1 += 1;
      return self.foo1;
   }

   /****************************************************************************
    * Public Exports
    ***************************************************************************/
   self.public = {
      doFoo1: self.doFoo1,
      doFoo2: self.doFoo2
   }

   self.constructor();
   return self.public;
}

preFoo = Foo();

function Bar() {
   this._foo1 = 15;
   this._foo2 = 'testing';
   this._foo3 = { i: 1, am: 2, a: 3, literal: 4 };
   this._foo4 = null;
}

Bar.prototype.doFoo1 = function () {
   return this._foo2;
}

Bar.prototype.doFoo2 = function () {
   this._foo1 += 1;
   return this._foo1;
}

preBar = new Bar();

Tests:

Instantiation - Closure
let foo = Foo();
Instantiation - Prototype
let bar = new Bar();
Utilization - Closure
let baz = preFoo.doFoo2();
Utilization - Prototype
let baz = preBar.doFoo2();
