将嵌套对象数组转换为对象数组的最佳方法

如何解决将嵌套对象数组转换为对象数组的最佳方法

const data = [
  {
    'UTMEH5': {
      descr: {
        ordertype: 'limit',pair: 'XBT/USD',price: '5000.00000',},status: 'open',vol: '0.00200000',{
    '3F2TYE': {
      descr: {
        ordertype: 'limit',price: '10000.00000'
      },]

const orders = data.map((order) => {
          return Object.entries(order).map(([key,value]) => ({
            orderid: key,pair: value['descr']['pair'],vol: value['vol'],price: value['descr']['price'],ordertype: value['descr']['ordertype'],status: value['status'],}))})
          
 console.log(orders)

通过上面的代码，我得到了这个：

[
  [
    {
      "orderid": "UTMEH5","pair": "XBT/USD","vol": "0.00200000","price": "5000.00000","ordertype": "limit","status": "open"
    }
  ],[
    {
      "orderid": "3F2TYE","price": "10000.00000","status": "open"
    }
  ]
]

但我想要这个：

[
    {
      "orderid": "UTMEH5","status": "open"
    },{
      "orderid": "3F2TYE","status": "open"
    }
]

对于重复的建议，我似乎可以使用 .flat()，但这似乎是获得我想要的东西的迂回方式。有没有更好更直接的方法？

解决方法

对于这种情况，您可以使用 flatMap() 代替 map()。

const data = [{
    'UTMEH5': {
      descr: {
        ordertype: 'limit',pair: 'XBT/USD',price: '5000.00000',},status: 'open',vol: '0.00200000',{
    '3F2TYE': {
      descr: {
        ordertype: 'limit',price: '10000.00000'
      },]

const orders = data.flatMap((order) => Object.entries(order).map(([key,value]) => ({
  orderid: key,vol: value['vol'],status: value['status'],...value['descr'],// you can use spread operator here for brevity as well
})))

console.log(orders)
