如何检查由分隔符分隔的两个字符串是否有匹配的单词

function checkMatchingWords(str1, str2, delimiter) {
  const words1 = str1.split(delimiter);
  const words2 = str2.split(delimiter);

  for (let word1 of words1) {
    for (let word2 of words2) {
      if (word1 === word2) {
        return true;
      }
    }
  }

  return false;
}

// 示例用法
const string1 = "apple,banana,orange";
const string2 = "pear,banana,grape";
const delimiter = ",";

const hasMatchingWords = checkMatchingWords(string1, string2, delimiter);
console.log(hasMatchingWords);  // 输出 true
