我有如下的对象数据数组，其中 ID 是对象嵌套数组中的重复键：

 const arr =  [
      {
        "First Name": "ABC",
        "Last Name": "XYZ",
        "Gender": "MALE",
        "Id": "123",
        "moreDetails": {
          "items": [
            {
              "Id": "123",
              "City": "BLR",
              "State": "KA"
            }
          ]
        }
      },
      {
        "First Name": "Test",
        "Last Name": "Me",
        "Gender": "FEMALE",
        "Id": "12345",
        "moreDetails": {
          "items": [
            {
              "Id": "12345",
              "City": "KAN",
              "State": "UP"
            }
          ]
        }
      }
    ]

期望以下格式的数据，其中 ID 现在只有一个条目并且嵌套数组也被展平：

[
  {
    "First Name": "ABC",
    "Last Name": "XYZ",
    "Gender": "MALE",
    "Id": "123",
    "City": "BLR",
    "State": "KA"
  },
  {
    "First Name": "Test",
    "Last Name": "Me",
    "Gender": "FEMALE",
    "Id": "12345",
    "City": "KAN",
    "State": "UP"
  }
]

我尝试使用Array.flat()and，Array.flat(Infinity)但无法处理此数据集。我也尝试使用简单的 for 循环，但没有得到预期的结果。有人能帮忙解决这里缺少的逻辑吗？

const result2 = [];
for (let key in arr) {
if (arr.hasOwnProperty(key)) {
  if(!typeof arr[key].moreDetails === 'object'){
    result2.push(arr[key]);
  }else{
    for(let key2 in arr[key].moreDetails.items){
      result2.push(arr[key2]);
    }
  }
}
}

我有以下格式的对象键值。

{
    "Code1": {
        "char10": "ch1",
        "number1": "1",
        "text1": "txt1"
    },
    "Code2": {
        "char2": "ch2",
        "num2": "2"
    },
    "Code3": {
        "text": "txt4"
    }
}

想要转换为这种格式：

{
  "Code1": [
    {
      "char10": "ch1",
      "number1": "1",
      "text1": "txt1"
    }
  ],
  "Code2": [
    {
      "char2": "ch2",
      "num2": "2"
    }
  ],
  "Code3": [
    {
      "text": "txt4"
    }
  ]
}

设法获得了有点相似的响应，但没有得到我想要的确切输出。

尝试了下面的代码片段但它返回的格式与预期不同。

Object.entries(payload).map((e) => ( { [e[0]]: e[1] } ))

以上片段的响应：

[
    {
        "Code1": {
            "char10": "ch1",
            "number1": "1",
            "text1": "txt1"
        }
    },
    {
        "Code2": {
            "char2": "ch2",
            "num2": "2"
        }
    },
    {
        "Code3": {
            "text": "txt4"
        }
    }
]
