偶尔写的工具函数

    const str111 = `“asdd”eeeeeeeeeeeeeee`;
    const filterStr = (str, ipt) => {
      if (!str.length || str === ipt || !ipt || !str.includes(ipt)) return str;
      let str1 = "",
        str2 = "";
      for (let i = 0; i < str.length; i++) {
        if (ipt.includes(str[i]) && !str1.includes(str[i])) {
          console.log("str[i] :>> ", str[i]);
          str1 += str[i];
        } else {
          str2 += str[i];
        }
      }
      return [str1, str2];
    };
    console.log("    filterStr() :>> ", filterStr(str111, `“asdd”`));
