Noticed some very interesting code in the one try todey file

[raisedeyebrowemoji]

`const urlParams = new URLSearchParams(window.location.search)
const NO_SECRET_MODE = urlParams.has("nosecret")
const NO_FOOLS_MODE = urlParams.has("nofools")
const UNLOCK_MODE = urlParams.has("unlock")
const SCALE = urlParams.get("scale") ?? 1
const DPR = urlParams.get("dpr") ?? devicePixelRatio
print('DPR:', DPR)
if (NO_SECRET_MODE) {
localStorage.setItem("secretHasAlreadyBeenRevealed", "true")
}

const secretHasAlreadyBeenRevealed = localStorage.getItem("secretHasAlreadyBeenRevealed")
`

I personally know nothing about coding and read the file for the flavor text comment at the beginning but what can this imply? What kind of secret is this and how do I activate it?
