Preparation code

 
<script>
Benchmark.prototype.setup = function() {
    Klass1 = function() {}
    Klass1.prototype.foo = function() {
      log('foo');
    }
    Klass1.prototype.bar = function() {
      log('bar');
    }
   
   
   
    var FooFunction = function() {
      log('foo');
    };
    var BarFunction = function() {
      log('bar');
    };
   
    Klass2 = function() {
      var foo = function() {
      log('foo');
    }, bar = function() {
      log('bar');
    };
      return function() {
        return {foo: foo , bar: bar}
      }
