JavaScript AngularJS Basics (1.x) Services in Angular Using Services To Get Data

JSON object being parsed into a string?

For some reason my JSON object is being parsed over using the $http.get service into a string? I have tried re-structuring it into a regular array, and it sill being translated as a string? I have no idea why it is doing this.

Here is my JSON object (document named cloudTerms.json):

[
    {category: "secondary",
    term: "test1" }
];

Here is my service and controller:

angular.js 
angular.module("todoListApp",[])

.controller("mainCtrl", function($scope, dataService){

    $scope.addTerm = function(){ };

    dataService.getCloudTerms(
        function(response) {            
            console.log(response.data);
            $scope.cloudTerms = response.data;
            console.log($scope.cloudTerms);
        }
    );

})

.service("dataService", function($http){

    this.getCloudTerms = function(callback){
        $http.get('data/cloudTerms.json')
        .then(callback);
    }

})

and here's my html:

      <div id="themeCloud" ng-controller="mainCtrl">

          <div class="output" ng-repeat="cloudTerm in cloudTerms">
            <h1>{{cloudTerm.category}}</h1>
            <h2>{{cloudTerm.term}}</h2>
              <hr/>
          </div>

          {{cloudTerms}}

      </div>

Again, keep in mind the data IS being successfully transferred over, but the application is rendering it as a string rather than an array. Thanks!

Try parsing the json before using it:

dataService.getCloudTerms(function(response) {            
  $scope.cloudTerms = JSON.parse(response.data);
});
