title: What is 'NodeJS' module in Node.js? (asking because it's so hard to google it)
body: <p>I was searching where nodejs <code>global</code> object comes from, and found that <code>global</code> object actually comes from a module called... <code>NodeJS</code>. What exactly is this module? Perhaps the objects in this module are auto-imported to the global context? Is there any document about this?</p>
  
  <p>The problem is that, because of its name <code>NodeJS</code>, it is so hard to google it to find where this is documented.</p>
