Delete object property doesn't work in Angular?

Question

Removing a object property using delete doesn't seem to work with angular. The object remains unchanged. The weird thing is that I can add properties to the object just fine.

Could it be because the object is exposed in $scope ? But how can I remove properties from it then?

This is my code

const {remote} = require('electron');

angular.module('myapp', []).service('db', function(){

  var data = remote.getGlobal('data');

  return {

    removeItem: function(item){
      console.log(delete data[item]); -> returns false!!
    }


  }

});

I'm calling the method from a controller:

$scope.removeAction = function(item){
  db.removeItem(item);
};

removeAction is called on ng-click of a button

Currently you're just modifying data object in db service. I don't see any variable references directly bounded to your $scope variable. Hence you have to fetch data once again from the db(service) as you want to see the changes on $scope variable.

$scope.removeAction = function(item){
  //may be you have to update data variable once again
  //data = remote.getGlobal('data'); //then removeItem
  db.removeItem(item);
  //retrieve latest list from `db` service once again.
  $scope.data = db.getData(); //assumed data is collection retrieved from db.
};

but it doesn't remove it in the db service either. I console logged it just after delete and it stays the same, and delete returns false

Are you sure you data object is updated when you trying to delete item??

nvm i found out why, its because of the electron global thing. if I replace that with some example object it works..
