    var infowindow = new google.maps.InfoWindow();

    var marker, i;

    for (i = 0; i < locations.length; i++) {  
      marker = new google.maps.Marker({
        position: new google.maps.LatLng(locations[i][1], locations[i][2]),
        map: map
      });

      google.maps.event.addListener(marker, 'click', (function(marker, i) {
        return function() {
          infowindow.setContent(locations[i][0]);
          infowindow.open(map, marker);
        }
      })(marker, i));
    }
  </script>
</body>
</html>

my controller


public function index()
    {
        $locations = Message::get()
        ->toArray();
        return view('welcome',compact('locations'));
    }

i don't know why my locations markers doesn't appear and when i run console.log(locations) return object not array

You don't need to use print_r here AFAIK. This should work as well

 <script type="text/javascript">
    var locations = <?php echo json_encode($locations); ?>;

    // Your javascript here
</script>

Note: Depending on what is in $locations you either get a javascript array or object. You can always loop over an object or get an array item from there.
