if (result.data) {
               $scope.dropDownListManager.add({ text: 'All', value: 0 });
               for (var i = 0; i < result.data.length; i++) {
                   $scope.dropDownListManager.add({
                       text: result.data[i][1],
                       value: result.data[i][0]
                   });
               }

What I have tried:

<pre> if (result.data) {
                $scope.dropDownListManager.add({ text: 'All', value: 0 });
                for (var i = 0; i < result.data.length; i++) {
                    $scope.dropDownListManager.add({
                        text: result.data[i][1],
                        value: result.data[i][0]
                    });
                }

By looking at the code, not clear why you need .map, it doesn't look like the code is trying to alter the object persona. it simply get the result from API and bind to the dropdown. Anyway, something like below should work. Refer below link for an example.

JavaScript

$.map( result.data, function( value, key ) {
   $scope.dropDownListManager.add({
                        text: key,
                        value: value
                    });

//  return '';
});

is that Jquery Map function will load data in dropdown faster?

I think performance wise should not make much different. You might need to test it out.

its not working for me...can you please modify below code and send it
$scope.loadManagerData = function () {
$scope.dropDownListManager = new kendo.data.DataSource();
//Fetch the Managers Dropdown list from the database
$http.get('/MigByManager/GetManagerDropdownList/' + projectId)
.then(function (result) {
if (result.data) {
$scope.dropDownListManager.add({ text: 'All', value: 0 });
for (var i = 0; i < result.data.length; i++) {
$scope.dropDownListManager.add({
text: result.data[i][1],
value: result.data[i][0]
});
}
}
},
