Setup

window.obj = {};
    for (var i = 0; i < 25; i++)
    obj[i] = Math.random();
    window.arr = [];
    for (var i = 0; i < 25; i++)
    arr[i] = Math.random();
    window.items1=[];
    items1 = [
      ['James Bond', 8, 40],
      ['Superman', 9999, 36]
    ];
    window.items2=[];
    items2 = [{
      Name: 'James Bond', strength: 8,
      coolness: 40
    }, {
      Name: 'Superman', strength: 9999,
      coolness: 36
    }];
