Refactor

[lukeeey]

I see this is quite an old project and is not really updated anymore. It would be nice to refactor it to use ES6 classes which would make the code a whole lot cleaner.

I would make my own package but i really like the git name 😂

Please feel free to refactor and improve the code! As long as all the tests still pass, it's easy to merge 😄
