  try {
    const params = req.params;
    const body = req.body;
    let result;

    console.log(params);
    console.log(body);

    Cat.forEach((cat) => {
      if (cat.id === params.id) {
        cat = body;
        result = cat;
      }
    });

    res.status(200).send({
      success: true,
      data: {
        cat: result,
      },
    });
  } catch (error) {
    res.status(400).send({

      error: error.message,
    });
  }

    console.log(params);
    console.log(body);

    Cat.forEach((cat) => {
      if (cat.id === params.id) {
        cat = { ...cat, ...body };  //cat에 body를 덮어씌움 (구조분해할당)
        result = cat;
      }
    });

    res.status(200).send({
      success: true,

        const newCat = Cat.filter((cat)=>cat.id !== params.id); 
        // filter는 조건에 일치하는 것들만 모아서 새로운 배열을 만듬
        res.status(200).send({
            success: true,
            data: newCat,

        });
