js takes a string of words and returns the highest scoring word.

function high(x){  // 1. split x by ' ' to an array.  const wordList = x.split(' ');    // 2. calculate each word score to another array.  const getScore = (word) => {    return word.split('').reduce((prevScore, currWord) => prevScore + currWord.charCodeAt(0) - 96, 0)  }  const scoreList = wordList.map(word => getScore(word));  // 3. get the highest score and index  let highestIndex = 0;  let highestScore = 0;  scoreList.forEach((score, i) => {    if (score > highestScore) {      highestIndex = i;      highestScore = score;    }  });    // 4. return the string of the highest score index of wordList  return wordList[highestIndex];}
