怎么替换数组中对象的属性

用es6
第一种: ...item根据你的需求,可要可不要

    let arr = [
      {id: 1, title: "绑定手机"},
      {id: 2, title: "实名认证"},
      {id: 3, title: "游戏分享任务"},
      {id: 12, title: "游戏体验任务"},
      {id: 13, title: "游戏时长任务"}
    ]
    const res = arr.map(item=>({...item, label: item.title, value: item.id}))
    console.log(res);

第二种: 比较傻瓜的

  let arr = [
      {id: 1, title: "绑定手机"},
      {id: 2, title: "实名认证"},
      {id: 3, title: "游戏分享任务"},
      {id: 12, title: "游戏体验任务"},
      {id: 13, title: "游戏时长任务"}
    ]
    let arrNew = arr.map((item) => {
      item.label = item.title
      item.value = item.id
      return item
    })
    console.log(arrNew);

好好生活-_-
