// ======== OUTPUT ========
/* Use print(message) for output.
   Default tag for message is <pre>. Use print(message,'div') to change containing element tag.

   Message can contain HTML markup. You may also tweak index.html and/or styles.css.
   However, please, REFRAIN from improving visuals at least until your code is reviewed
   so code reviewers might focus on a single file that is index.js.
