Utilizing array methods with promises in returned arrays: A guide

Hey everyone, I'm facing a situation where I have an array of objects in the database. I used $http.get to retrieve this data and I understand that it returns as a promise, which means I can't directly use push() or forEach(). However, I really need to utilize these methods with the array. One solution could be transferring the values to another array and then applying the desired methods. How should I go about solving this? Thanks

$http.get('/api/itens').success(function(itens){
  $scope.itens= itens;
  socket.syncUpdates('itens', $scope.itens);    
});

var arr = []

$scope.itens.forEach(function(value){
  arr.push(value.name);

});

Answer №1

If items is in the form of an array, you have the option to utilize a forEach loop on it. However, this action should occur solely once it has finished executing its operations.

$http.get('/api/items').success(function(items){
  $scope.items = items;
  socket.syncUpdates('items', $scope.items);    

var newArray = []

  $scope.items.forEach(function(value){
    newArray.push(value.name);

  });
});
