Benchmark created on October 25, 2013

Setup

var MyType = function MyType() { }
    
    var obj_dispatch = {}
    obj_dispatch[String] = function(str) { return str; }
    String.prototype.runFn = function() { return this; }
    obj_dispatch[MyType] = function(obj) { return obj; }
    MyType.prototype.runFn = function() { return this; }
    
    function runFn(obj) {
      if (typeof(obj) === "string") {
        return obj_dispatch[String](obj);
      } else {
        return obj_dispatch[obj.constructor](obj);
      }
    }
    
    
    var prim = "Hello";
    var str = new String("Hello");
    
    var my_obj = new MyType();
