Prototype vs Module pattern performance (v202)

Revision 202 of this benchmark created by Chirayu Krishnappa on

Description

Removed iterations in tests, because jsperf already does that for us. And renamed variables to be more meaningful to us humans. And other cosmetic changes.

The most important thing to remember is to use the right tool for the job. All these tests do is reference an object with a complex memory allocation. When you don't need something fancy, you're better off using a regular old object

Setup

function TraditionalPrototypeClass() {
    }
    
    TraditionalPrototypeClass.prototype.foo = function() {
    };
    
    TraditionalPrototypeClass.prototype.bar = function() {
    };
    
    function ModulePatternClass() {
        this.foo = function() {
        };
        
        this.bar = function() {
        };
    }
    
    var ModuleCachePatternClass = (function () {
        function foo() {
        }
        
        function bar() {
        }
        
        return function () {
            this.foo = foo;
            this.bar = bar;
        };
    }());
    
    var standardObject = {
        foo: function(){
        },
        bar: function(){
        }
    };
