You can try with momentjs library:

var dateArray = ["09/09/2009", "16/07/2010", "29/01/2001"],
    format = 'DD/MM/YYYY',
    minDate = moment(dateArray[0], format),
    minDateKey = 0;

for (var i = 1; i < dateArray.length; i++) {
  var date = moment(dateArray[i], format);
  if (minDate > date) {
    minDate = date;
    minDateKey = i;
  }
}

alert(minDateKey);
