Prototype vs Module pattern performance (v208)

Revision 208 of this benchmark created on

Setup

function log(l){
        return l+l;
    }
    
    Klass1 = function() {
    this.testProp = "Hello World";
    };
    Klass1.prototype.foo = function() {
      log(this.testProp);
    };
    Klass1.prototype.bar = function() {
      log(this.testProp);
    };
    
    
    Klass2 = function() {
      return {
        testProp: "Hello World",
        foo: function() {
          log(this.testProp);
        },
        bar: function() {
          log(this.TestProp);
        }
      };
    };
    
    
    var FooFunction = function(v) {
      log(this.testProp);
    }, BarFunction = function(v) {
        log(this.testProp);
      };
    function Klass3() {
    this.testProp = "Hello World";
    
        this.foo = FooFunction;
        this.bar = BarFunction;
      }
    
    var Klass4 = (function () {
        function Klass4() {
            this.hello = "Hello World";
        } 
        Klass4.prototype.foo = function () {
            log(this.hello);
        }
        Klass4.prototype.bar = function () {
            log(this.hello);
        }
        return Klass4;
    })();
