You know you've ascended to a higher plane of existence when you discover higher-order functions. That moment when you realize you can just... pass a function into another function? Pure euphoria. It's like unlocking a secret level in the game of programming. Suddenly your code goes from a bunch of repetitive nonsense to elegant, reusable magic. Array.map(), callbacks, middleware patterns—it all clicks. You feel like a functional programming wizard who just learned their first spell. The universe makes sense now. Then you spend the next three months trying to find excuses to pass functions as arguments to everything, even when it's completely unnecessary. "Should I make a function that takes a function that returns a function?" Yes. Always yes.
