Checking entity access

In this recipe, we will demonstrate how to check whether the current user has access to view an article node.

   use Symfony\Component\HttpFoundation\Request;

   class ArticleController extends ControllerBase {

     public function get(NodeInterface $node):

       JsonResponse {
