AngularJS Json restructure

Question

I can get a json from some services in Angular function, however, there are too many unnecessary things so I am trying to restructure Json to include only data I need.

$http({
            method: 'GET',
            url: 'from some service'}   

        }).success(function(data, status) {

           //this is Json data where I need to remove many things
           $scope.data = data;  

           //this is Json data I need
           $scope.processedJson = [];
      }

Let's say $scope.data is

{
   "points":[
      {
         "address":"balh",
         "lat":123,
         "long":456
      },
      {
         "address":"balh",
         "lat":321,
         "long":543
      },
      {
         "address":"balh",
         "lat":432,
         "long":333
      }
   ]
}

And $scope.processedJson which is ultimately what I need to have is

[
   {
      "lat":123,
      "long":456
   },
   {
      "lat":321,
      "long":543
   },
   {
      "lat":432,
      "long":333
   }
]

How do I need to run some looping to extract the data I need?

You can use a forEach

$scope.processedJson = [];
angular.forEach($scope.data.points, function (val) {
    $scope.processedJson.push({
        lat: val.lat,
        long: val.long
    });
});
