What is $applyAsync, and how can it help in improving AngularJS performance?

$applyAsync defers expressions until the next digest cycle, reducing digest cycle triggers and consolidating updates. It’s valuable in scenarios with frequent updates, as it optimizes performance by minimizing digest overload, making applications more responsive.

$scope.incrementAsync = function() {
  $scope.$applyAsync(() => {
    $scope.counter++;
  });
};
