title: How can I update NodeJS and NPM to their latest versions?
body: <h3>I just installed <strong>Node.js</strong> &amp; NPM (Node Package Manager)</h3>
  <p>I installed NPM for access to additional <strong>Node.js</strong> Modules.</p>
  <p>After I installed Node.js &amp; NPM I noticed that neither were the latest versions available.</p>
  <p><strong>I would like to know:</strong> <em>How do I upgrade Node.js, NPM, and my Node.js Modules to their latest versions?</em></p>
  <p>Do I need to uninstall Node.js &amp; NPM and reinstall the latest versions?</p>
