Find the Longest Word in a String

// My favourite
function findLongestWordLength(str) {
	return Math.max(...str.split(' ').map((word) => word.length));
}

// OR

function findLongestWordLength(str) {

	// if words has multiple elements, remove the first element
	// and recursively call the function
	return Math.max(words[0].length, findLongestWordLength(words.slice(1).join(' ')));
