Countdown Recursion

Q. Write an algorithm that counts down with recursion.

const countdown = function (n) {
 if (n === 0) return;
 console.log(n);
 countdown(n - 1);
}
countdown(10);
// should be 10, 9, 8, 7, 6, 5, 4, 3, 2, 1

1. If n === 0, return nothing.
2. Output n.
3. Use countdown function and set the parameter (n-1).

n = 10
? n === 0 // False
console.log(n) // 10
countdown(9)
n = 9
? n === 0 // False
console.log(n) // 9
countdown(8)
...
n = 1
? n === 1 // False
console.log(n) // 1
countdown(0)
n = 0
? n === 0 // True
