Someone really looked at Rock Paper Scissors and thought "yeah, I can solve this with string concatenation." The genius move here is adding the computer's choice (1, 2, or 3) to the player's choice (also 1, 2, or 3) and checking if the result equals specific strings like "11", "22", "33" for draws, or "12" for rock vs paper. The problem? They're concatenating numbers as strings instead of doing actual math. So when computer picks 1 and player picks 2, you get "12" (the string), not 3 (the number). It's technically functional but hilariously cursed. It's like using a sledgehammer to crack an egg - sure it works, but everyone watching is uncomfortable. The real kicker is they're treating what should be simple arithmetic logic (winner = (player - computer + 3) % 3) like some kind of bizarre string matching puzzle. Props for creativity, but my code reviewer would have questions.

Every developer has that phase where they think reinventing the wheel is somehow more efficient than using a battle-tested library. Sure, why use a well-documented, community-supported JavaScript library when you could spend three weeks creating your own utils folder that's basically a worse version of Lodash? The best part? By the time you're done, you've created 1000 utility functions that do things like "add two numbers" and "check if a string is empty" - functions that probably already exist in the standard library. But hey, at least you understand every line of code in your bloated codebase, right? Nothing says "professional developer" quite like maintaining your own implementation of leftPad() . Pro tip: Your future self will hate current you when they have to debug your custom date formatting function at 2 AM instead of just importing moment.js or date-fns.
