The Monday Morning Code Amnesia

Ah yes, the infamous "Friday code" phenomenon. Nothing quite like staring at your monitor on Monday morning, squinting at some bizarre algorithm you apparently wrote while possessed by the spirit of caffeine and deadlines. That code might as well be written in hieroglyphics. The worst part? You left zero comments because Friday-you was absolutely convinced Monday-you would remember exactly what that nested ternary inside a map function inside a reduce was supposed to do. Spoiler alert: you don't.
