AngularJS undefined value outside of $http.get function [duplicate]

I have a controller and I make an http request to get some data. Data arrives but when I try to use it it's like it does not exist at all. I have used the same method in a previous project and everything worked well. I have been trying to fix this for a couple days but no luck. It seems like there is a problem with the scope or the order of execution is not the right one.

Here is my code:

  .controller("myCtrl", ['$scope', '$http', function($scope, $http) {
    console.log("myCtrl");

    var vm = this;

    $http.get('/get-data').then(function(response) {
      vm.data = JSON.stringify(response.data);
      console.log(vm.data); //returns correct json data
    })

    console.log(vm.data); //returns undefined

  }])

Further information: There are multiple controllers in the module.
