title: Multilanguage express app
body: <p>I wonder what would be the best way to implement multiple versions / languages of the same content in the same layout in express.</p>
  
  <p>Should I just do this?</p>
  
  <pre><code>app.get("/", function(req, res) {
      res.render(language + "/index");
  });
  </code></pre>
  
  <p>Or is there a smarter / better way?</p>
