Question

我有一个这样的对象数组：

  {
    "sCode": "1010",
    "PCode": "1011",
    "category": "Diagnostic",
    "procedure": "Oral assessment for patients up to the age of 3 years inclusive. ",
    "serviceClassification": "First Dental Visit/Orientation",
  },

我正在尝试按category分组并创建一个名为children的数组，然后该数组具有另一个嵌套的serviceClassification分组的子项数组

所需的输出

[
  {
    "id": "Diagnostic",
    "text": "Diagnostic",
    "children": [
      {
        "id": "FIRST DENTAL VISIT/ORIENTATION",
        "text": "FIRST DENTAL VISIT/ORIENTATION",
        "children": [
          {
            "id": 0,
            "text": "01011 - Oral assessment for patients up to the age of 3 years inclusive."
          }
        ]
      }

我已经尝试了几个小时，这是我尝试过的代码示例：

Answer 1

我首先将其按类别分组，然后按serviceClassification分组，剩下的转换工作留给您。
