title: Generate a Unique Order Number (Human Readable) in JavaScript
body: <p>What I'm struggling to find a way to create a Unique Readable Order Number for eCommerce.
  Most of them out there are very long and very hard to read.</p>
  
  <p>My backend for this eCommerce is firebase, and the document IDs are too complicated to use as an ID.</p>
  
  <p>Are there any know standards/examples I can follow? </p>
