Greetings, Push.
Thanks for your consideration. I've created a solution to your code assessment, found in demo.js. You can view a live version here. I chose jsBin to avoid configuring Webpack for this one small file. However, I wanted to include this version of the code to give you a better sense of my workflow (es6/babel/eslint, etc.).
Thank you again for taking the time to review this submission. I'll look forward to hearing from you soon!
Sincerely,
Nick
