How to delete item from an array of object using angularjs?

i wanted to delete index from array if rest service response return true , so in below case lets say we have true from rest service i wanted to delete object where id is 'RA_ATTST_LANGUAGE` from array. I tried below code but its not deleting what is missing ?

main.js

MessageAdminNotificationFactory.getAttestationLanValidation().then(function(response){
        var data = response.data;
        console.log('attestation',data);
        if(data){
          angular.forEach($scope.adminDataSource,function(value,$index){
            if(value.id === 'RA_ATTST_LANGUAGE'){
              $scope.adminDataSource.splice($index, 1);
            }
            console.log('dropdown',value.id);
          });
        }
      });

$scope.adminDataSource = [{
    "uid": null,
    "index": 0,
    "selected": null,
    "expanded": null,
    "id": "RA_PLTFRM_NOTIF",
    "text": "Platform Maintenance Notification",
    "parentId": null,
    "items": null
}, {

$scope.adminDataSource = $scope.adminDataSource.filter(
  function(value){
     return value.id !== 'RA_ATTST_LANGUAGE';
})

Array.filter is the way to go. filters out anything that evaluates to false;

Iterate the array from end to start

for(var i=$scope.adminDataSource.length-1;i>=0;i--){
    var value = $scope.adminDataSource[i];
    if(value.id === 'RA_ATTST_LANGUAGE') {
       $scope.adminDataSource.splice(i,1);
    }
}

This way it doesn't matter if the array shrinks while you iterate.
