Tips for creating an array within an AngularJS Service and effectively sharing it across two controllers

I have two controllers, FirstController and SecondController, along with a service defined as follows:

app.factory('Data', function(){
    return [];
});

In both controllers, I am utilizing the service in this manner:

app.controller("FirstController", function($scope, $http, Data) { 

// Using $http.get() to retrieve a JSON array and storing it in Data.myArray

}

app.controller("SecondController", function($scope, $http, Data) { 

// Attempting to access the array stored in the Service 
$scope.recoveredArray = Data.myArray;
// Performing operations on the recoveredArray...

}

Finally, displaying the recoveredArray from SecondController in the html view.

Thank you for your help!

Your application must include a function that returns an object containing the property myArray.

app.factory('data', function() {
    return {
      myArray: []
    };
});
