AngularJS, что является лучшим подходом в отношении производительности и обработки проверки

Question

Мой код работает нормально, но я ищу лучший подход для обработки проверки.Я новичок в angularjs и мне нужен hel для улучшения моих навыков кодирования.

У меня есть 5 сценариев в коде для проверки всех сценариев.

Сначала проверьте правильность assignment.startDate с procurement.startDate

Второе, assignment.startDate с procurement.endDate

Третье, assignment.endDate с assignment.startDate

В-четвертых, assignment.endDate with procurement.startDate

В-пятых, assignment.endDate с procurement.endDate

$timeout(function () {
                    if (moment(vm.assignment.startDate) < moment(vm.procurement.startDate)) {
                        $scope.assignmentForm.startDate.$setValidity('mindate', false);
                        $scope.assignmentForm.startDate.$setTouched();
                        $scope.assignmentForm.startDate.$validate();
                        vm.endDateValidationMessage = "Start Date of Assignment Agreement cannot be earlier than Start Date of Procurement Agreement";
                    } else {
                        $scope.assignmentForm.startDate.$setValidity('mindate', true);
                        $scope.assignmentForm.startDate.$setTouched();
                        $scope.assignmentForm.startDate.$validate();
                    }

                    if (moment(vm.assignment.startDate) > moment(vm.procurement.endDate)) {
                        $scope.assignmentForm.startDate.$setValidity('maxdate', false);
                        $scope.assignmentForm.startDate.$setTouched();

                        $scope.assignmentForm.endDate.$setTouched();
                        $scope.assignmentForm.endDate.$validate();
                        vm.endDateValidationMessage = "End Date of Assignment Agreement cannot be earlier than Start Date of Assignment Agreement";
