Implement Codacy Recommendations

[confused-Techie]

Alright, apologies to @DeeDeeG for the fact I just don't seem to stop making PPM PRs lol.

This PR should be the last one of the ones I've had semi ready to go, and implements the majority of the low hanging fruit flagged on codacy.

Thanks again to anyone able to review this one, and hopefully I'll calm down in this repo afterwards

Sure 👍 .

Tests pass.

Diff looks good.

INFORMATIONAL (NO ACTION NEEDED):

"For fun" (out of curiosity), I checked that the statusCode is in fact a number, and not a string, when the URL is wrong. (I deliberately edited the hard-coded target URL to be wrong, logged the typeof response.statusCode here, and I got:

typeof response.statusCode is: number

Script behaves as expected with === 404 as opposed to === "404" which bugs out.

Overly thorough way of saying this change is good 👍

Thanks a ton for double checking! My intuition in this space said they should be numbers and I didn't question it. So I'm happy you've actually checked

I'm surprised how many unused require()s there are in this repo. Must have been a fair amount of churn throughout development.

Lol, no worries. I happen to be available to review these at the moment. Good to see some, er, winter cleaning around this repo, heh.

Thanks for the review @DeeDeeG!

And yeah it's surprising how much junk is left over in this repo, so I'm more than happy to just delete it lol
