This can also be run here: repl.it

I have various versions of this assessment saved on repl.it. I chose to go with this option because I'm going to need to explain my thought process to another developer and using more vanilla js allows me to describe it more thoroughly. Prior to going to prod, this code could be cleaned up, comments removed, etc.

I have a (somewhat) cleaned up version using ES6 here: repl.it
