Json 角度8 Typescript展平嵌套数组

我有嵌套的JSON数据，需要将其展平，以便在一个表中向用户显示所有选项，而不显示下拉列表

数据看起来像这样

0:
ID: 4
Date: "2019-08-09T00:00:00"
Data:
Year: 2019
Identification: "F31073"
nestedArray: Array(1)
   0:
      array1ID: "31"
      array1Code: "073"
      nestedArray2: Array(4)
      0:
        array2info: 24
        nestedArray3: Array(8)
          0:
          array3Identifier: "ECF5EE44-50E1-4F07-AB38-CF7A60A6276F"
          array3Number: 31
          arrayThreeIndicator: "N"
          nestedArray4: Array(1)
             0:
             array4Info: "31"
             array4Code: "073"

我看过很多解决方案，但没有一个能为我提供一个平面的数据数组

这里更新的是我试图展平的JSON数据，以便对每个嵌套数组复制之前的字段，并且在没有嵌套数组的情况下，所有数据都是可见的

非常感谢您的帮助

如果嵌套数组键相同，则可以递归执行：

type NestedData={nested:NestedData[]}[]
函数展平（嵌套数据：嵌套数据）{
设展平=[]；
对于（嵌套数据的常量{nested，…restData}）{
flatted.push（restData）；
如果（！nested | |！nested.length）继续；
展平=展平.concat（展平（嵌套））
}
返回平直；
}  
常数展平=展平（数据）；

你明白了。

谢谢你的回答……这就是使用你的解决方案返回的结果{ID:4，日期：“2019-08-09T00:00:00”，数据：{…}你可以看到最后一个元素是一个尚未展平的数组。你能包含一个实际数据的JSON表示吗？仍然是一个很大的丑陋的…可能是这种格式吗？`````{“a”：{“b”：{“c”：{}}```
