Eliminate the array from the data retrieved through an http request in AngularJS

Currently, I am making an http call to retrieve data from a database. This process involves calling 6 different types individually.

        $scope.getAll = function() {
        var url = 'http://someurl/';
        var allObjects = [];
        $scope.types.forEach(element => {
            http({
                method: 'GET',
                url: url + element.name
            }).then(function successCallback(response) {
                allObjects.push(response.data);
            },function errorCallback(response) {
               // this doesn't apply to my issue
            });
            $scope.allObjects = allObjects;
            }

This returns a JSON object structured as follows:

[{},

[{ "label":"myLabel",
        "types": {
           "source":{"url":"some url, "storage":"some storage"}}},
     { "label":"myLabel",
        "types": {
           "source":{"url":"some url, "storage":"some storage"}}}],[{ more objects}],[{ more objects}],],

All objects have the same structure with nested arrays. My current issue is that during each iteration of the type, it adds it as an array of objects. I want it to be added as a new object instead of an array of objects. For example:

Current Output:

[{}, [{first iteration}], [{second iteration}], [{etc}]]

Desired Output:

[{first iteration}, {second iteration}, {etc}]

To simplify an array of arrays, you can utilize the Array.prototype.flat() method, which condenses nested arrays to a specified depth level. In your scenario, the default depth is set to 1.

var arr = [
   {}, 
   [
     { 
        test: 1 
     }
   ], 
   [ 
     { 
        second: 2 
     }
   ], 
   [
     {
        etc: 3
     }
   ]
];
console.log(arr.flat());

This function essentially flattens the arrays within the main array up to a single level, but if you have deeper nested arrays that need flattening, you would adjust the depth parameter to 2.

The empty object elements will remain after flattening, so it's advisable to add logic to remove them post-flattening.
