title: Create node list from a single node in JavaScript
body: <p>This is one of those it seems so simple, but I cannot come up with a good way to go about it.</p>
  
  <p>I have a node, maybe <code>nodelist = document.getElementById("mydiv");</code> - I need to normalize this to a node list. And not an array either: an actual, bona-fide <code>nodeList</code> object.</p>
  
  <p><strong>Not</strong> <code>nodelist = [document.getElementById("mydiv")];</code></p>
  
  <p>No libraries, please.</p>
