Revision 2 of this benchmark created by hrj on

Setup

var rawData = ["yeah", "this is", "a", "wonderful", "blue", "world", "But", "its", "poisoned", "with", "hate", "and", "apathy" ];
    
    var sortedStrings = [];
    for (i = 0; i < 1000; i++) {
      sortedStrings.push(rawData[Math.random()*(rawData.length-1) | 0]);
    }
    
    sortedStrings.sort();

Teardown


    unSortedStrings = [];
