FUNDAMENTALS
Simple, given a string of words, return the length of the shortest word(s).
String will never be empty and you do not need to account for different data types.
const findShort = s => {
const words = s.split(/\s+/)
const wordsSortedAscendingLength = words.sort((a, b) => a.length - b.length)
return wordsSortedAscendingLength[0].length
}
