title: router.post('/', controller) vs router.route('/').get(controller)
body: <p>What's the difference between writing routes:</p>
  <pre><code>//in this style
  router.route('admin').get(getAllAdminsController).post(createAdminController)
  </code></pre>
  <p>and this type of writing:</p>
  <pre><code>router.get('admin', getallAdminsController);
  router.post('admin', createAdminController);
  </code></pre>
