Revision 3 of this benchmark created on September 17, 2014

Setup

var Foo1 = function(prop) {
      this.bar = prop;
    };
    
    function Foo2(prop) {
      this.bar = prop;
    }
    
    var foo3 = {
      bar: ""
    };
    
    function foo4(prop) {
      return {
        bar: prop
      };
    }
    
    function foo5(prop) {
      return Object.freeze({
        bar: prop
      });
    }

Test runner

var y = {bar: 42};

var y = new Foo1(42);

var y = new Foo2(42);

var y = Object.create(foo3);
y.bar = 42;

var y = foo4(42);

var y = foo5(42);
