How to sort objects by date ( ascending ) only those with var === true .
On the rest, sorting would not pay attention.
For example, through ng-repeat="arr in array | orderBy: 'date'". But this applies to all objects.

Answer 1

The easiest way is to make two different arrays and display them separately (if I understand correctly).
Let the original array, as in fiddle

original = [
  {id: 1, name: 'test_1', date: '2018-12-9', var: true},
  {id: 2, name: 'test_2', date: '2018-12-2', var: false},
  {id: 3, name: 'test_3', date: '2018-12-6', var: true},
  {id: 4, name: 'test_4', date: '2018-12-8', var: false},
  {id: 5, name: 'test_5', date: '2018-12-10', var: true},
  ];

Then a new date-sorted array with var === true:
Array with other dates without sorting:

unsortedArray = original.filter( next => !next.var)
