var socket = new WebSocket('ws://html5hacks.com/socket');

// Once the socket connection is opened ... send a message to the server

  socket.send('Hello, Html5');
};

// Log any data pushed from the server
socket.onmessage = function(event) { 
  console.log(event.data); 
}

// Once the socket connection is closed ... log closed to the console.
