如何用对象过滤对象数组并创建新对象？

Question

我有一个对象数组

const myData = [
    {
        "paiteint1": [
            {
                "status": "healthy",
                "date": "2022-05-01",
                "hour": "12AM"
            },
            {
                "status": "healthy",
                "date": "2022-05-01",
                "hour": "1AM"
            },
            {
                "status": "need attention",
                "date": "2022-05-01",
                "hour": "2AM"
            },
            {
                "status": "healthy",
                "date": "2022-05-01",
                "hour": "3AM"
            },
            {
                "status": "need attention",
                "date": "2022-05-01",
                "hour": "4AM"
            },
            {
                "status": "critical",
                "date": "2022-05-01",
                "hour": "5AM"
            },
            {
                "status": "healthy",
                "date": "2022-05-01",
                "hour": "6AM"
            },
            {
                "status": "critical",
                "date": "2022-05-01",
                "hour": "7AM"
            },

        ],
        "paiteint2": [
            {
                "status": "healthy",
                "date": "2022-05-01",
                "hour": "12AM"
            },
            {
                "status": "healthy",
                "date": "2022-05-01",
                "hour": "1AM"
            },
            {
                "status": "need attention",
                "date": "2022-05-01",
                "hour": "2AM"
            },
            {
                "status": "healthy",
                "date": "2022-05-01",
                "hour": "3AM"
            },
            {
                "status": "need attention",
                "date": "2022-05-01",
                "hour": "4AM"
            },
            {
                "status": "critical",
                "date": "2022-05-01",
                "hour": "5AM"
            },
            {
                "status": "healthy",
                "date": "2022-05-01",
                "hour": "6AM"
            },
            {
                "status": "critical",
                "date": "2022-05-01",
                "hour": "7AM"
            },
        ]
    }
  ]

并且需要根据他的健康状况将json以上的obj转化为以下的甲酸

需要对象

const manipulatedData = [
        {
            "paiteint1 heathy": {
                //all healthy status obj
            },
            "paiteint1 need attention": {
                //all need attention status obj
               
            },
            "paiteint1 critical": 
            {
              //all critical status obj
            },
            "paiteint2 heathy": {
                //all healthy status obj
            },
            "paiteint2 need attention": {
                //all need attention status obj
               
            },
            "paiteint2 critical": 
            {
              //all critical status obj
            },
        }
    ]

我已经尝试在 obj 过滤器 reduce 上进行映射，但无法获得所需的 o/p。我也在寻找任何其他方法，如果有人可以建议这对我来说会很好。

    ],
    paiteint2: [
      {
        status: "healthy",

      {

      },
      {

        date: "2022-05-01",
        hour: "7AM",
      },
    ],
  },
];

const manipulatedData = [];

myData.forEach((d) => {
  Object.keys(d).map((p) => {
    return d[p].map((s) => {
      manipulatedData[`${p} ${s.status}`] = d[p].filter(
        (sp) => sp.status === s.status
      );
    });
  });
});

console.log(manipulatedData);

结果

[
  'paiteint1 healthy': [
    { status: 'healthy', date: '2022-05-01', hour: '12AM' },
    { status: 'healthy', date: '2022-05-01', hour: '1AM' },
