Prototype vs Module pattern performance (v238)

Revision 238 of this benchmark created by TysonG 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

var three = threeFn;
    var four = fourFn;
    var five = five();
    var six = six();
    
    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(){
        }
    };
    
    var standardObjectFnCall = {
        foo: one(),
        bar: two()
    };
    
    var standardObjectDeclaredFnCall = {
        foo: three(),
        bar: four()
    };
    
    var standardObjectFnVar = {
        foo: five,
        bar: six
    };
    
    function one() {
    }
    function two() {
    }
    
    function threeFn() {
    }
    
    function fourFn() {
    }
    
    function five() {
    }
    
    function six() {
    }
