javascript - Unable to sort an array by date with React

Question

I am unable to sort an array by date. I tried many different things but couldn't get it to work. An array consists of objects with a last_updated field that has a value formatted like this: 24/1/2021 @ 13:21:2.

I tried sorting the array before executing .map():

chats.sort(function (a, b) {
  return (
    new Date(b.last_update) - new Date(a.last_update)
  );
});

This does not work and I honestly don't know why. Is this because of the @ in the date?

Answer 1

Try this:

chats.sort(function (a, b) {
  return new Date(b.last_update).getTime() - new Date(a.last_update).getTime();
});
