title: Including a .js file in node.js
body: <p>I am trying to include this script in my app: <a href="http://www.movable-type.co.uk/scripts/latlong.html" rel="noreferrer">http://www.movable-type.co.uk/scripts/latlong.html</a></p>
  
  <p>I have saved it in a file called lib/latlon.js, and I am trying to include it like this:</p>
  
  <pre><code>require('./lib/latlon.js');
  </code></pre>
  
  <p>How should I go about including a JS library like this?</p>
