Recursion from Scratch - countdown with recursion

recursive-countdown.js

// Counting down is:
const countdown = number => {
 	// Logging `'HAPPY NEW YEAR!'` if we're at zero.
	if (number === 0) {
		console.log('HAPPY NEW YEAR!')
	} else {
		// Logging the current number and counting down the next number down otherwise.
		console.log(number)
		countdown(number - 1)
	}
}
