i want to get the latest created Item any ideas ?

Answer 1

The item with the biggest ID is the latest created item.

function compare(a,b) {
  if (a.id < b.id)
     return -1;
  if (a.id > b.id)
    return 1;
  return 0;
}

arr.sort(compare);
var latestItem = arr[arr.length - 1];

You can also compare the dates created in the Compare fuction and it will give the same result.

function compare2(a,b) {
  var date1 = new Date(a.created);
  var date2 = new Date(b.created);
  if (date1 < date2)
     return -1;
  if (date1 > date2)
    return 1;
  return 0;
}

arr.sort(compare2);
var latestItem = arr[arr.length - 1];
