Recursion: An important intermediate level concept for nested processing

	// Recursion: a function may call itself and work with the return value.
	// It can do this multiple times before returning the original execution

	const getDeepTotal = function deepTotal(inputArray) {
	let total = 0
	inputArray.forEach((el)=>{
	total += Array.isArray(el) ? deepTotal(el) : el
	})
	return total
	}

	{
	input: "test-one",
	answer: "One",
	},
	{
	input: "test-two",
	helper: (input, callback) => {
