    return new Date(start.getTime() + Math.random() * (end.getTime() - start.getTime()));
}

var arrObjects = [];
for(var i = 0; i < 100000; i++){
  arrObjects.push({value:randomDate(new Date(2012, 0, 1), new Date())});
}

function getRandomInt(max) {
  return Math.floor(Math.random() * Math.floor(max));
}

var arrIntegers = [];
for(var i = 0; i < 100000; i++){
