在字符串javascript代码中查找不能处理最后一个单词的最长单词

function findLongestWord(code) {
  let longestWord = "";
  let longestLength = 0;

  const words = code.split(" ");

  for (let i = 0; i < words.length; i++) {
    const word = words[i].replace(/[^a-zA-Z]/g, ""); // 去除非字母字符

    if (word.length > longestLength) {
      longestLength = word.length;
      longestWord = word;
    }
  }

  return longestWord;
}

const code = "在字符串javascript代码中查找不能处理最后一个单词的最长单词";
const longestWord = findLongestWord(code);
console.log("最长的单词是：" + longestWord);
