I want to sort an object called metadata below:

const metadata = {
  glucose: {
    name: 'Glucose',
    units: 'mg/dL',
  },
  height: {
    name: 'Height',
    units: '"',
    longUnit: 'Inches',
  },
  weight: {
    name: 'Weight',
    units: 'lbs',
    longUnit: 'Pounds',
  },
  bmi: {
    name: 'BMI',
  },
  pulse: {
    name: 'Pulse',
  },
  temperature: {
    name: 'Temperature',
    units: 'F',
    longUnit: 'Fahrenheit',
  },
  respiration_rate: {
    name: 'Respiration Rate',
  },
  o2_saturation: {
    name: 'O2 Saturation',
    units: '%',
  },
}

Metadata needs to be sorted on name for each vital in allVitals's taken_on value. So in this example, according to the taken_on time, the weight vital take_on was later than the glucose taken_on. So in the metadata sort where weight would be before glucose. The allVitals array can have more than just two vitals, it could have vitals of all types and multiple of them (i.e, multiple pulse vitals, multiple weight vitals)

const allVitals = 
[
    {
        "patient_id": 79,
        "vital_type_id": 4,
        "value": "171",
        "taken_on": "2022-11-17T13:19:00.000-06:00",
        "vital_type": {
            "id": 4,
            "name": "weight",
            "units": "pounds",
            "created_at": "2022-11-17T13:52:00.375-06:00",
            "updated_at": "2022-11-17T13:52:00.375-06:00"
        },
        "notes": null,
        "source": "patient_device",
        "id": 1399,
        "time_recorded": true,
        "severity": null,
        "formatted_severity": "-",
        "vital_attributes": {},
        "vital_status": "valid"
    },
    {
        "patient_id": 79,
        "vital_type_id": 6,
        "value": "9.76",
        "taken_on": "2022-11-17T11:07:00.000-06:00",
        "vital_type": {
            "id": 6,
            "name": "glucose",
            "units": "mg/dL",
            "created_at": "2022-11-17T13:52:00.360-06:00",
            "updated_at": "2022-11-17T13:52:00.360-06:00"
        },
        "notes": null,
        "source": "patient_device",
        "id": 1366,
        "time_recorded": true,
        "severity": "critical_low",
        "formatted_severity": "Critical - Low",
        "vital_attributes": {},
        "vital_status": "valid"
    }
]

The Expected result would be

const metadata = {
  weight: {
    name: 'Weight',
    units: 'lbs',
    longUnit: 'Pounds',
  },
  glucose: {
    name: 'Glucose',
    units: 'mg/dL',
  },
  height: {
    name: 'Height',
    units: '"',
    longUnit: 'Inches',
  },
  bmi: {
    name: 'BMI',
  },
  pulse: {
    name: 'Pulse',
  },
  temperature: {
    name: 'Temperature',
    units: 'F',
    longUnit: 'Fahrenheit',
  },
  respiration_rate: {
    name: 'Respiration Rate',
  },
  o2_saturation: {
    name: 'O2 Saturation',
    units: '%',
  },
}

As this shows that since weight was taken_on later than glucose it comes first in metadata object

So I solved it with the help of @This Guy so I gave him an upvote

const OrderedVitalsArray = allVitals
    .sort((v1, v2) => moment(v2.taken_on).diff(moment(v1.taken_on)))
    .map((e) => {
      return e?.vital_type?.name
    })

  const OrderedMetadata = OrderedVitalsArray.reduce((current, item) => {
    current[item] = metadata[item]
    return current
  }, {})

CodePudding user response：

Build a list of order, then loop through that, use the items as a key against the original list and rebuild the order.

const metadata = {
  glucose: {
    name: 'Glucose',
    units: 'mg/dL',
  },
  height: {
    name: 'Height',
    units: '"',

  },
  weight: {
    name: 'Weight',
    units: 'lbs',
    longUnit: 'Pounds',
  },
  bmi: {
    name: 'BMI',
  },
  pulse: {
    name: 'Pulse',
  },
  temperature: {
    name: 'Temperature',
    units: 'F',
    longUnit: 'Fahrenheit',
  },
  respiration_rate: {
    name: 'Respiration Rate',
  },
  o2_saturation: {
    name: 'O2 Saturation',
    units: '%',
  },
}
