title: What does the .listen() method in express look like?
body: <p>I read the docs, concerning the .listen() method, used in express. I can <strong>USE</strong> the method and setup a server that is listening to HTTP requests.</p>
  <p>However, since I am fairly new to coding, I find it difficult to grasp whats really happening when using the .listen() method. The high level explanation &quot;listening for connections&quot; didn't help me.</p>
  <p>I think, this could be made easier if I could actually see the function instead of only calling it.</p>
  <p>Any help is very much appreciated</p>
