title: NodeJS: Where does console.debug output go?
body: <p>Where does console.debug output go? And how can it be enabled to appear on the stdout, like console.log?</p>
  
  <p>I looked it up in <a href="https://nodejs.org/api/console.html" rel="noreferrer">https://nodejs.org/api/console.html</a>, but it does not appear.
  If, however, I run node from the command line, it is defined.</p>
  
  <pre><code>node
  console.debug
  [Function: debug]
  console.debug('but where does this go?')
  </code></pre>
  
  <p>So the function is defined, but (by default) doesn't output to stdout or stderr.  I'm guessing there is a flag to enable to turn it on.</p>
