app.get - is there any difference between res.send vs return res.send : <p>I am new to node and express. I have seen app.get and app.post examples using both "res.send" and "return res.send". Are these the same? </p>

<pre><code>var express = require('express');
var app = express();

app.get('/', function(req, res) {
  res.type('text/plain');
  res.send('i am a beautiful butterfly');
});
</code></pre>

<p>or</p>

<pre><code>var express = require('express');
var app = express();

app.get('/', function(req, res) {
  res.type('text/plain');
  return res.send('i am a beautiful butterfly');
});
</code></pre>
