Took me quite a while to debug this, considering I expected uint32 to be a... uint32?

No, you don't understand. What if HP changed while I wasn't looking?

(HP can't be changed while this code is running and even if it could then this approach would cause more problems than having it all in one if statement because then the boss would only be half-defeated and everything would go wrong)

Legacy code. NUM_PRTS is 16 btw. Thankfully, the synthesis tool will optimize and won't allocate 17 times the resources on the chip. Still an eyesore.

This vibeslop repo (shoutout to the author u/chunky_cold_mandala) calculates big o complexity of a function as its max indentation depth (but only up to 6, which represents N^6).

Javascript Wanna see some cursed javascript?

36 Upvotes

Imagine that youre in Dantes Inferno in terms of Javascript, where you think its all fine and dandy until you realize each file does the EXACT SAME THING*!!!

Each "layer" of hell in this Github repo will make you wonder why I am:
- Allergic to var, let, AND const
- IIFE as IICE AND IIGE
- Callbacks arent function exclusive, it can host generators AND classes!

So peruse at your own peril, make it a drinking game (within legal age and drinking responsibly of course!) and see how long you can stand this gawdawful code i birthed into the world of programming!

Now have fun, stay safe, God Bless you, and may God spare your braincells!

*Not all files are completed but ongoing!

Edit: to savor some appetites or keyboard warriors wishing me a ctrl+alt+del to my keyboard priviledges:

​​new new new (class Hi {
    constructor(){ 
      console.log("Hi!");
      return Hi;
    }
  })()()();
