Potential issue when using Express without Jade
<p>I'm trying to use Express for my project, and the recommended way for views is using Jade template engine like this:</p>

<pre><code>/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Express' });
});
</code></pre>

<p>but I don't want to rewrite my existing HTML file, so I use <code>sendfile</code> like this:</p>

<pre><code>/* GET home page. */
router.get('/', function(req, res, next) {
  res.sendfile("./views/hello.html");
});
</code></pre>

<p>and it work just fine!</p>

<p>But my question is, is there some potential issue that I didn't notice if I use <code>sendfile</code> to replace <code>render</code>? Like performance or security issue?</p>

<p>And if there isn't, then why the recommended way is to use Jade?</p>
