how to make global variable and print outside function

Question

I am using AngularJS & RESTangular. Is it possible to print or get return from function from below code?

This is my controller code

var items = $scope.items = [] 
Restangular.all("items").getList().then(function(serverItems) {
    items = serverItems;
    $scope.items = serverItems
});

// PRINTING ITEMS HERE IN CONSOLE
console.log(items);
console.log(serverItems);

}

You can call the function by passing the $scope.items.

var items = $scope.items = [];
Restangular.all("items").getList().then(function(serverItems) {
    items = serverItems;
    $scope.items = serverItems;

    // successful getting response from the server, now print or manipulate the data
    printItems(items);
});

// PRINTING ITEMS HERE IN CONSOLE
function printItems(items) {
    console.log(items);
    // do data manipulation
}

In this case, you will wait for getting the response, and then do the data manipulation on the response data.
