如果在数组中找到字符串中的单词，则替换该单词

function replaceWordInArray(arr, targetWord, newWord) {
  for (let i = 0; i < arr.length; i++) {
    if (typeof arr[i] === 'string') {
      const words = arr[i].split(' ');
      for (let j = 0; j < words.length; j++) {
        if (words[j] === targetWord) {
          words[j] = newWord;
        }
      }
      arr[i] = words.join(' ');
    }
  }
  return arr;
}

// 示例用法
const array = ['Hello world', 'This is a test', 123, 'Replace word'];
const targetWord = 'world';
const newWord = 'universe';

const result = replaceWordInArray(array, targetWord, newWord);
console.log(result);
