Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    var obj = {
      fn: function(a,b) {return a + b; }
    };
    
    var fn = obj.fn,
        fnJsBound = jsBind(obj, fn),
        fnBound = function() {};
    
    if (fn.bind) {
      fnBound = fn.bind(obj);
    }
    
    function jsBind(self, fn) {
      return function() {
        return fn.apply(self, arguments);
