const myString = 'Find the longest word from the given string.'
const myStringArr = myString.split(' ')

function longestWord(myStringArr) {
  let longestWord = ''
  for (let word of myStringArr) {
    if (word.length > longestWord.length) {
      longestWord = word
    }
  }
  return longestWord
}
