Nested-callbacks Memes

You know you've gone too far when your code looks like it's actively trying to escape the screen. That beautiful cascade of nested .map() , .split() , .reduce() , and .filter() calls is what happens when you refuse to use variables because "functional programming is cleaner." The cherry on top? That innocent little { red: 0, green: 0, blue: 0 } buried in there like it's totally normal to be six levels deep in method chaining. And let's not even talk about the triple nested reduce at the end that's doing... something with products and sums? Sure, it probably works. Sure, it's technically one expression. But good luck debugging this when it breaks at 2 AM, or explaining it to your teammate who just wants to understand what "cube[1]" means without a PhD in callback archaeology. Sometimes the real puzzle isn't Advent of Code—it's reading your own code three days later.
