我怎么能按时间戳排序这个数组,最快的方法是什么(数组有很多条目)？
我的阵列
myList = new Array();
myList[0] = {};
myList[0]['title'] = 'I am really new';
myList[0]['timestamp'] = 1317039046;
myList[0]['date'] = '2011-09-26T12:10:46+00:00';
myList[1] = {};
myList[1]['title'] = 'I am the oldest';
myList[1]['timestamp'] = 1315656646;
myList[1]['date'] = '2011-09-10T12:10:46+00:00';
myList[2] = {};
myList[2]['title'] = 'I am older';
myList[2]['timestamp'] = 1316866246;
myList[2]['date'] = '2011-09-24T12:10:46+00:00';
myList[3] = {};
myList[3]['title'] = 'I am old';
myList[3]['timestamp'] = 1316952646;
myList[3]['date'] = '2011-09-25T12:10:46+00:00';
