【问题描述】：

我收到了来自对象数组的 api 调用的响应。我想通过删除嵌套对象“公司”来修改每个对象，并将其直接嵌套到主对象。有没有办法快速做到这一点？

{
    "ip": "127.0.0.1",
    "hostname": "test.compute.amazonaws.com",
    "city": "São Paulo",
    "region": "São Paulo",
    "country": "Brazil",
    "loc": "-33.5375,-36.31",
    "org": "AS16509 Amazon.com, Inc.",
    "postal": "01000-000",
    "timezone": "America/Sao_Paulo",
    "company": {
      "name": "Amazon Data Services Brazil",
      "domain": "amazon.com",
      "type": "hosting"
    },
    "countryCode": "BR"
}

我想把json改成这个

{
    "ip": "127.0.0.1",
    "hostname": "test.compute.amazonaws.com",
    "city": "São Paulo",
    "region": "São Paulo",
    "country": "Brazil",
    "loc": "-33.5375,-36.31",
    "org": "AS16509 Amazon.com, Inc.",
    "postal": "01000-000",
    "timezone": "America/Sao_Paulo",
    "name": "Amazon Data Services Brazil",
    "domain": "amazon.com",
    "type": "hosting"
    "countryCode": "BR"
}

【解决方案1】：

我已经使用过这个功能，但我正在检查是否有更快的方法。

const formatObj = (obj) =>{
  obj.name = obj.company.name;
  obj.domain = obj.company.domain;
  obj.type = obj.company.type;
  delete obj.company
  return obj
}

【解决方案2】：

var newList = listFromAPI.map((object) => {
delete object.company
return {...object};
});

这里 newList 将包含所有没有公司属性的对象列表
