Another guess just based on the terms is it could be a method that throws your json object into a black hole and returns the version of the object that is stretched out to infinity.

Though that’s just an optical illusion, in reality the object would be ripped apart by the gravity or extreme radiation, depending on whether it was a small or large black hole.

Your guesses are more useful, but I can’t fathom what goes on in the mind of JavaScript devs.
