Ajax polling in Laravel

The following html will keep fetching data from the controller function load_notification_list() and refresh the dataTable content every setInterval() function's mentioned milliseconds.

This isn't always never a good practice however this takes no time to setup if compared to other alternatives like SSe's or WebSockets

Controller:

public function get_notifications()
    {
      try
      {
        $data = [];
        $data['notifications'] = Notification::all();

        return view('admin.notification.view', $data);
      }
      catch(Exception $e)
      {
        abort(400);
      }
    }


public function load_notification_list(Request $request)
    {
      $inputs     = $request->all();
        $start      = 0; $limit = $this->perpage; 
        $column     = @$inputs['columns'][@$inputs['order'][0]['column']]['data'];
        $dir        = @$inputs['order'][0]['dir'];

      $notif_list['data'] = [];

      $notifications = Notification::take($limit)->skip($start);
      $notifications = $notifications->get();

        foreach ($notifications as $key => $notif) {
            switch ($notif->type) {
                case '0':   
                    $status='Pending';
                    break;
                case '1':
                    $status='Active';
                    break;

                    break;
