Angular, why is $scope not visible outside of the request?

Question

API

Why is $scope not visible outside of the request?
How can I reach him?

Companies.count.query({}, function success(data) { 
              $scope.count = data; 
              console.log($scope.count.c)         //print 4415
          })
      console.log($scope.count.c)         //undefined

Part of the service:

count:
                $resource('api/companies/count', {}, {
                    'query':  {method:'GET',isArray:false},
                }),

Answer 1

Maybe because the request is asynchronous, and at the time of the call (where undefined appears) - $scope.count is really undefined ?

Answer 2

Because a function successis a callback that is called after the request has completed. In your second example, the variable is аassigned an empty object (or an array, if it is in the options isArray) which is filled with data after the request has completed and the data is visible in the console, because by the time you view them, the request has already completed.
