chore: rephrase some comments

[Uzlopak]

First of all, I am not a PC advocate, but it is better to rephrase these comments.

@KhafraDev
As I change the wording of the comment in util.js but still "claim" it is your note and thus implying it being your words, can you please approve or comment on this?
