arguments performance (v13)

Revision 13 of this benchmark created on

Setup

var res = []
  var slice = [].slice;
  function f1(){
      for(var i = 0, l = arguments.length; i < l; i++){
          res.push(arguments[i])
      }
  }
  
  function f2(){
      var args = arguments
      for(var i = 0, l = args.length; i < l; i++){
          res.push(args[i])
      }
  }
  
  function f3(){
      var len = arguments.length;
      res = new Array(len);
      for (var i = 0; i < len; i++)
           res[i] = arguments[i];
  }
  
  function f4(){
      res = Array.prototype.slice.call(arguments);
  }
  
  function f5_helper(){
      res = arguments;
  }
  function f5(){
      f5_helper.apply(null, arguments);
  }
  
  function f6() {
    res = 1 <= arguments.length ? slice.call(arguments, 0) : [];
  };

Teardown
