我生成的对象是这样的：
[{
"device": {
"_id": "5d25f9d2dc4aea7838b0aaa1",
"serialNumber": "100000100215",
"patientRiskStatus": "high",
"createdAt": "2017-04-16T01:22:00.000Z",
"updatedAt": "2020-01-01T05:29:19.632Z"
},
"firstName": "userName"
}]
我想将此对象结构转换为：
[{
"_id": "5d25f9d2dc4aea7838b0aaa1",
"serialNumber": "100000100215",
"firstName": "userName",
"patientRiskStatus": "high",
"createdAt": "2017-04-16T01:22:00.000Z",
"updatedAt": "2020-01-01T05:29:19.632Z",
}]
这是我的代码——
var filteredDevices = []
var result = []
if (user.role === 'Nurse') {
devices.forEach((device) => {
filteredDevices.push({
device: device,
firstName: "userName"
})
result = filteredDevices.map(({ device, ...rest }) => ({
...rest,
...device
}))
})
}
我尝试了下面建议的解决方案，它在代码片段示例中看起来不错.js但我的节点只是行为不同，我不确定为什么。
我在尝试解决方案时得到的结果如下。 不知道为什么它给了我这么长的结果。

使用Array.map()迭代数组。在回调中，解构device属性，并使用 rest 语法获取对象的其余部分。
通过将device和原始对象的其余部分展开到新对象中来重建对象。
const arr = [{"device":{"_id":"5d25f9d2dc4aea7838b0aaa1","serialNumber":"100000100215","patientRiskStatus":"high","createdAt":"2017-04-16T01:22:00.000Z","updatedAt":"2020-01-01T05:29:19.632Z"},"firstName":"userName"}]
const result = arr.map(({ device, ...rest }) => ({
...rest,
...device
}))
console.log(result)
