Benchmark: Prototype vs simulated private

Tests:

Simulated private
(function (root, factory) { var moduleName = 'Test'; if (typeof define === 'function' && define.amd) { define(moduleName, factory); } else if (typeof exports === 'object') { module.exports = factory(); } else { root[moduleName] = factory(moduleName); } }(this, function (moduleName) { function Test(element) { this.element = element; var a = function () { return "a" }; var b = function () { return "b" }; var c = function () { return "c" }; (function init() { console.log(a()); }()); } return Test }));
Prototype
(function (root, factory) { var moduleName = 'Test'; if (typeof define === 'function' && define.amd) { define(moduleName, factory); } else if (typeof exports === 'object') { module.exports = factory(); } else { root[moduleName] = factory(moduleName); } }(this, function (moduleName) { function Test(element) { this.element = element; } Test.prototype.a = function () { return "a" }; Test.prototype.b = function () { return "b" }; Test.prototype.c = function () { return "c" }; return Test }));
