JavaScript对象

Question

如何将obj对象的key与obj2的key对比，相等将obj的值填写到obj2的standard的值里面，形成res

onst obj = {
      "hz": "12",
      "hw": {
        "cm": "21",
        "m": "11"
      },
      "fr": {
        "cm_U": "12",
        "m_S": "22"
      }
    }

    const obj2 = {
      hz: {
        name: 'a',
        data: [{
          note: '',
          avg: {
            value: '',
            unit: '%'
          },
          standard: {
            value: '',
            unit: '%'
          }
        }]
      },
      hw: {
        name: 'b',
        data: [{
            note: 'cm',
            avg: {
              value: '',
              unit: '%'
            },
            standard: {

用下面的代码处理obj2

//const obj =。。。。
//const obj2 =。。。。

   for (let attr in obj) {
        if (typeof (obj[attr]) == 'object') {
            Object.keys(obj[attr]).forEach(key => {
                let obj2item = obj2[attr].data.find(i => i.note == key);
                if (obj2item) obj2item.standard.value = obj[attr][key];
            })
        }
        else {
            for (let item of obj2[attr].data) item.standard.value = obj[attr];
        }
    }
    console.log(obj2);
