ng-repeat with track by over multiple properties

Question

I have a problem with angular ng-repeat directive. Currently I work on some project where from the API I get a list of items (some times it could be 1k items) and this list

As the comment suggested you could try something like this:

In your controller:

$scope.itemTracker= function(item) {
  return item.id + '-' + item.description;
}


This might help with the number of DOM elements being re-rendered when the list changes.
