find element in obj vs array (v33)

Revision 33 of this benchmark created on

Setup

var obj = {},
        arr = [],
        count = 0;
    for (var i = 0; i < 10000; i++) {
      arr.push('wowow124.23' + i);
      obj['wowow124.23' + i] = 1;
    }
    
    
    function in_array(needle, haystack) {
      for (var i = 0, maxi = haystack.length; i < maxi; ++i) {
        if (haystack[i] == needle) {
          return true;
        }
      }
      return false;
    }
    
    function include(needle, haystack) {
      return (haystack.indexOf(needle) != -1);
    }
