使用map和reduce（如果可能）javascript对动态JSON键进行分组

我想对json的动态对象键进行分组。每个关键点的对象值将分组到各自的关键点

我尝试使用map和reduce对其进行分组，但结果并没有按预期进行分组

这是我的JSON对象

var data = [
  {
    "type": 6,
    "data": {
      "error": {
        "cause": {
          "root": {

                      }
                    }
                  }
                }
              }
            }
          }
        }
      }
    },
    "status": true
  }
]

这是我尝试过的代码，但没有得到我想要的结果

var x = data.map((e) => {
  var el = {}
    el[e.data.error.cause.root.Extracted.Body.Error.ErrorString] = 
    [e.data.error.cause.root.Extracted.Body.Error.info];

    return el;
  })

 console.log(x);

我得到的结果是：

 [
   {
     "NotFound": {....}
   },
   {
     "NotFound": {....}
   },
   {
     "SystemFailure": {....}
   },
   {
     "SystemFailure": {....}
   },
   {
     "Unknown": {....}
   },
 ]

我预期的结果是：

[
 {
   "NotFound": [
     {
       "Error": {
         "errorDesc": "Data Not Found",
         "subs": {
           "attrib": {
              "subs_name": "123com",
              "subs_no": 4
         }
       }
     },
     {
       "Error": {
         "errorDesc": "Company Not Found",
         "subs": {
         "attrib": {
            "subs_name": "QRS",
            "subs_no": 4
         }
       }
     }
   }
  ]
 },
 { 
   "SystemFailure": [
      {
       "Error": {
          "errorDesc": "Internal server error",
          "subs": {
              "attrib": {
              "subs_name": "ABC",
              "subs_no": 2
            }
          }
      },
      {
        "Error": {
            "errorDesc": "Insufficient Data",
            "subs": {
               "attrib": {
                  "subs_name": "DEF",
                  "subs_no": 3
               }
            }
      }
   ]
 },
 {
    "Unknown": [
       {
          "Unknown": {
            "desc": "UnknownError",
            "subs": "GHI"
          }
       }
    ]
 }
]

您可以

减少

数组。使用唯一的

ErrorString

键创建累加器对象。将值设置为与键具有相同

ErrorString

的对象。然后根据

ErrorString

添加每个

info

对象。使用“获取分组值作为数组”

const data=[{type:6，data:{error:{原因：{root:{Extracted:{Body:{error:{143]，ErrorString:“NotFound”，info:{error:{error:{error:{未找到数据，{attrib:{subsu name:“123com”，subsu no:4}}}}}}}}}}}}}，状态：true}，{type:6，数据：{错误：{原因：{提取：{Body:{error:{错误：{Body:{error:{错误：{founded:{Found Found Found Found Found Found Found Found“未找到公司”，subs:{attrib:{subs_name:“QRS”，subs_no:4}}}}}，状态：true}，{type:6，数据：{error:{restracted:{Body:{error:{error:“123”，ErrorString:“SystemFailure”，信息：{errorDesc Internal server error:{error:“内部服务器错误”，subs:{attrib:{subs:{subs:{subs:{subs_name:“ABC”，subs:{attrib:{no:2}，状态：Extracted Body:{error:}，数据类型：true:}，错误：{{Error:{ErrorCode:“123”，ErrorString:“SystemFailure”，info:{Error:{errorDesc:{errorDesc:“数据不足”，subs:{attrib:{subs:”DEF”，subs:{subs:”no:3}}}}}}}，status:true}，{type:6，Data:{Error:{原因：{根：{提取：{Body:{Error:{Error:{ErrorCode:“999”，ErrorString:“未知”，info:{未知：{desc Unknown:{状态：}，subs:{GHI:}，状态：}true}；
const merged=data.reduce（（acc，o）=>{
const e=o.data.error.cause.root.Extracted.Body.error；
acc[e.ErrorString]=acc[e.ErrorString]|{[e.ErrorString]：[]}；
acc[e.ErrorString][e.ErrorString]。推送（e.info）
返回acc；
}, {})
常量输出=对象值（合并）；
console.log（output）

谢谢@adiga！你能给我解释一下每行代码是如何工作的吗？通过对代码的评论？我对如何在json中使用reduce并不太熟悉。
