Compile-time Memes

Someone really woke up and decided to implement FizzBuzz using TypeScript's type system at compile time. Not in regular code, mind you—in the type system itself . They're encoding numbers in base 15, doing string manipulation with template literals, and recursively building types that somehow output "Fizz", "Buzz", or "FizzBuzz" based on divisibility rules. All of this happens before a single line of JavaScript even runs. The result? Absolutely zero runtime value, maximum engineering flex. It's like using a Formula 1 car to go grocery shopping—technically impressive, completely impractical, and you'll confuse everyone in the parking lot. But hey, at least your FizzBuzz bugs will be caught at compile time, which is more than most production codebases can say.
