Mathematician 2 kinda blew my mind, kinda obvious, just can’t believe I was never taught or thought about it.

TDD

const max12 = (x, y) => {
    if (x === 1 && y === 2) {
        return 2;
    } else if (x === 7 && y === 4) {
        return 7;
    } else {
        return x;
    }
};

Why use const max = (x, y) => x > y ? x : y instead of function max(x, y) { return x > y ? x : y } ?
