Prototype vs Module pattern performance

JavaScript performance comparison

Revision 135 of this test case created

Info

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

Preparation code

 
<script>
Benchmark.prototype.setup = function() {
    function TraditionalPrototypeClass() {
    }
    TraditionalPrototypeClass.prototype.foo = function() {
    };
    TraditionalPrototypeClass.prototype.bar = function() {
    };
   
    var o1 = new TraditionalPrototypeClass();
   
    function Constructor() {
        this.foo = function() {
        };
       
        this.bar = function() {
        };
    }
    var o2 = new Constructor();
   
    var o6 = (function () {    
        return {
            foo: function () {},
            bar: function () {}
        }
    })();
   
    var o3 = (function () {
        var foo = function () {};    
        var bar = function () {};
       
        return {
            foo: foo,
            bar: bar
        }
    })();
   
    var standardObject = {
        foo: function(){
        },
        bar: function(){
        }
    };
    var o4 = standardObject;
   
    var o5 = {
        foo: function(){
        },
        bar: function(){
        }
    };
};
</script>
