Javascript reduce()在字符串中查找最短的单词

function findShortestWord(str) {
  // 将字符串拆分为单词数组
  const words = str.split(' ');

  // 初始化最短单词为第一个单词
  let shortestWord = words[0];

  // 遍历单词数组，比较每个单词的长度
  for (let i = 1; i < words.length; i++) {
    if (words[i].length < shortestWord.length) {
      shortestWord = words[i];
    }
  }

  return shortestWord;
}

const sentence = "JavaScript reduce() method is used to reduce the array into a single value.";
const shortest = findShortestWord(sentence);
console.log(shortest); // 输出 "is"
