Group by matching data id and order by another data attribute

Is it possible to group a number of divs by matching data-id and order it by another data attribute. Can this be done with underscorejs or plain javascript?

      ID: 62 Order 1
      ID: 59 Order 1
      ID: 59 Order 3

You can sort your div on id and orderby attribute.

$(function() {
  $("#parentID div").sort((a,b) => {
      return $(b).data('id') - $(a).data('id') || $(a).data('orderby') - $(b).data('orderby');
  }).appendTo('#parentID');
});



  ID: 71 Order 2
  ID: 71 Order 3
  ID: 71 Order 1
  ID: 62 Order 2
  ID: 62 Order 1
  ID: 59 Order 1
  ID: 59 Order 3
  ID: 59 Order 2

Use this script

$("#parentID div.child").sort(function(a, b) {
  return $(a).data("id") - $(b).data("id");
}).appendTo("#parentID");
