一道js问题求助一下

Question

//1.需求遍历listData,将数组key和对象key相匹配，如果匹配则将对象的value赋值给数组的value
  let listData= [
    { name: "张三:", key: "authenNo",value:''},
    { name: "李四:", key: "extendedRepair" ,value:''},
    { name: "赵恶:", key: "newCarSaleDate", value:''},
    { name: "王五:", key: "lastAuthenDate" ,value:''},
    { name: "笨蛋:", key: "gap" ,value:''},
  ];
  let Obj={
    authenNo:'我才不是张三呢',
    extendedRepair:'我才不是李四',
    lastAuthenDate:'我才不是王五',
    newCarSaleDate:'我才不是赵恶'
  },

最后的操作结果应为：
listData= [

    { name: "张三:", key: "authenNo",value:'我才不是张三呢'},
    { name: "李四:", key: "extendedRepair" ,value:'我才不是李四'},
    { name: "赵恶:", key: "newCarSaleDate", value:'我才不是赵恶'},
    { name: "王五:", key: "lastAuthenDate" ,value:'我才不是王五'},
    { name: "笨蛋:", key: "gap" ,value:''},
  ];

Answer 1

//不支持 ?? 就用 || 代替下
//listData.forEach(item => item.value = Obj[item.key] ?? item.value)
listData.forEach(item => item.value = Obj[item.key] || item.value)
