Welcome

Thanks for applying to Vyte. If we've sent you this exercise, you've already made it through the first step of our selection process so congrats!

How to use this repo

Clone it (don't fork it)
Solve the challenges and commit at least once per level (more if you think it's appropriate)
Zip it and send it back to us (make sure to include the .git folder)

Solve this challenges in Javascript (ES6 / ES2015 and later versions will be appreciated).
If you have a question or think something needs clarification, just make a reasonable assumption and explain it as a comment in your code.
We don't expect you to build an HTTP API around those classes or to plug an actual database to them.
We require you to complete at least level 1-3, though level 4 is expected. Level 5 is a bonus is you have time to spare (and always a good practice)
