title: Emit to Socket IO socket.id
body: <p>I am trying to emit to a particular socket ID:</p>
  
  <pre><code>socket(user[playID]).emit('correct', data);
  </code></pre>
  
  <p>But I'm getting:</p>
  
  <pre><code>TypeError: object is not a function
  </code></pre>
  
  <p>if I log out <code>user[playID]</code> I do get a valid socket ID.</p>
  
  <p>Appreciated!</p>
  
  <p>Here is my setup in case I'm missing something:.    </p>
  
  <pre><code>// Tell Socket.io to pay attention
  servio  = io.listen(server);
  
  // Tell HTTP Server to begin listening for connections on port 3250
  sock    = server.listen(3250);
  </code></pre>
