Like za_creature said you can use a language more towards the YOLO end of the spectrum - more Go or Python or JavaScript than assembly or Rust.
Your commit history shows you had an issue of high background CPU use. You probably wouldn't have it in a manually coded implementation.
You might want to change the way you phrase this idea. I think you meant that Go/Python/JS are more "YOLO-friendly languages" (you'll get into far less trouble if you write slop in them). My initial reading was the opposite. It sounded like you were saying the languages themselves are the slapped together garbage.
Assembly is most certainly not "YOLO-friendly", but is more YOLO.
