Building a Tiny JS World (kottans#272)

* Add index.js

* Replace all with ES5 syntax

I Got Check-list from github-actions bot, where there are required requirements. With ES6 it was more interesting (Previous commit).

* Add ES6 classes, add some objects in a secret society

* Return to previous ES5 version

* Changes after review. Delete arr variable, delete for in loop.

+   However, please, REFRAIN from improving visuals at least until your code is reviewed
