Programmer Humor

I think this is just ofuscated code from one of the npm supply chain attacks

it's de-obfuscated, a human didn't write it (in that form) thankfully

Peer Review Reviews?

So there's some data its concatenating from some lists and running some checks on. If one if the checks succeeds it runs a function called clearInfo, I don't know js so idk if that's a built-in or if they defined it elsewhere in the script. If that check fails it runs clearInterval. This is all wrapped in a function called setInterval, and it looks like if all the checks succeed and the interpreter isn't moved to a different section of code by those functions called earlier then it will set whatever this interval is to 10000, presumably milliseconds. That's the big block in the middle.

The top block calls some code referencing a document, which appears to be stored as a list, index 12 is referenced and another obfuscated argument is applied to it.

The bottom block appears to be defining a function that will interact with the document referenced above. Calling the function showInfo and presumably concatenating and formatting some data into a pretty output for a user to get info regarding the document being referenced.

Someone who actually knows js could probably tell you more, I know python and c++ and this looks kinda like python but the syntax is a bit different so I could be way off

C doesn't have the function keyword
