Someone really looked at FizzBuzz and said "you know what this needs? A dependency tree deeper than my existential dread." Instead of writing basic arithmetic and conditionals like a normal person, they've installed an npm package for literally everything. Need to check if a number is divisible by 5 and 3? There's a package for that. Need to increment by one? Package. Need a for loop? Believe it or not, also a package. This is what happens when your bundle size is measured in gigabytes and your node_modules folder achieves sentience. The code is technically solving FizzBuzz, but at what cost? Your CI/CD pipeline now takes 45 minutes just to install dependencies, and you're one npm audit away from discovering 247 critical vulnerabilities in is-divisible-by-3 . Fun fact: The entire JavaScript ecosystem can be summarized as "why write code when you can install someone else's code that does the same thing but with 50 transitive dependencies?"
