title: app.set('views', __dirname + '/views') in Express & node.js
body: <p>I'm confused with the app.set() method.
  As far as I know, app.set() is like this</p>
  
  <pre><code>app.get('title');
  // =&gt; undefined
  
  app.set('title', 'My Site');
  app.get('title');
  // =&gt; "My Site"
  </code></pre>
  
  <p>but in tutorials, make 'views' folder and use like this.</p>
  
  <pre><code>app.set('views', __dirname + '/views')
  app.get('/') or app.get('/admin')
  </code></pre>
  
  <p>shouldn't it be like this? </p>
  
  <pre><code>app.get(views)
  </code></pre>
