title: Socket.io countdown synchronously?
body: <p>On my server I call two emits at the same time, which looks like this.</p>
  <pre><code>if (songs.length &gt; 0) {
      socket.emit('data loaded', songs);
      socket.broadcast.to(opponent).emit('data loaded', songs);
  }
  </code></pre>
  <p>The one is for <strong>opponent</strong> and the other for <strong>himself</strong>.</p>
  <p>Once the data is loaded a countdown should appear for both players on my android app. For me it is <strong>important</strong> that they see the same number at the same time on their screen. To be precise it should run synchronized. How can I do this?</p>
