I'm An Independent Coder And I Don't Need No Library

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.
