find element in obj vs array (v35)

Revision 35 of this benchmark created by Koolpin on

Description

slightly better math

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) {
      var i = haystack.length
      while (i--) {
        if (haystack[i] == needle)
          return true;
      }
      return false;
    }
    
    function include(needle, haystack) {
      return (haystack.indexOf(needle) != -1);
    }
