Witness generation code comments and vars instead of let or const

[Pfed-prog]

Gm, excuse me for bothering with not really related to Circom issue. But code report by gitroll says that my repository contains too many code smells.
The repository:
https://github.com/paris-geo-hackers/ParisCircuits

Code smells

The code smells are mostly related to comments within the witness file and for loops

I have also linted the repo and a lot of lines got updated, please, if you have some spare resources. Help us, developers.
