javascript - 使用 node.js 连接和聚合 json 响应数据

Question

我尝试了不同的方法，谁能解释我错在哪里？

我想根据各自的团队汇总团队成员。我尝试了下面的代码，但是无法获得正确的值。我认为在获取值时变量存在一些问题，但我只是不理解代码。谁能解释一下吗？

下面是我的代码:“data”是查询后返回的对象。

      var groups = []
      var Members = []

      for (var i = 0; i < data.length; i++) {

          var team = data[i].UnitId.BlockName;
          var member = { "Name" : data[i].Name, "Mobile" : data[i].Mobile }
          Members.push(member);
          console.log('Members are: '+JSON.stringify(Members));
          //if(data[i].UnitId.BlockName === team){
            var new_obj = { "Team" : team, Members};
            groups.push(new_obj);
          // }
      }

      console.log('Groups: '+JSON.stringify(groups));
      //------------------------------------

      let grouped = {};
      groups.forEach(({Team, Members}) => {
        grouped[Team] = grouped[Team] || {Team, Members: []};
        if (grouped[Team].Members.includes(Members.Name,Members.Mobile))
          grouped[Team].Members.push(Members.Name,Members.Mobile);
        // grouped[id].medal_count = `${(+grouped[id].medal_count)+ (+medal_count)}`;
      });
      grouped = Object.values(grouped);

      console.log(JSON.stringify(grouped)); 

输出:

{
    "grouped": [
        {
            "Team": "EasilyDone",
            "Members": []
        },
        {
            "Team": "BrainItOn",
            "Members": []
        }
    ]
}

期望的输出:

{
    "grouped": [
        {
            "Team": "EasilyDone",
            "Members": 
                     [
                         {
                                "Name" : "Dhairya"
                         }
                     ]
        },
        {
            "Team": "BrainItOn",
            "Members":
                     [
                         {
                                "Name" : "raj"
                         }
                     ]
        }
    ]
}

DATA LOOKS LIKE THIS

我认为你想做的是:

let grouped = {};

groups.forEach(({Team, Members}) => {
  grouped[Team] = { Team, Members };
});

此外，您的代码非常复杂。我建议您学习如何以更简洁的方式编写 Javascript。
