Proper use of app.set in express?
<p>I am currently following <a href="https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens" rel="nofollow">https://scotch.io/tutorials/authenticate-a-node-js-api-with-json-web-tokens</a>. However, I do not understand the need for ...</p>

<pre><code>app.set('superSecret', config.secret);
</code></pre>

<p>... when you could just continue using <code>config.secret</code>. Can someone kindly explain this to me? Much appreciated.</p>
