Methods
# static iterator() → {void}
It uses setTimeout to create a delay of 1 second between each count. The function decrements the counter, logs the current count, and calls itself until the counter reaches 0. When the counter reaches 0, the process exits.
A recursive function that manages the countdown timer.
