filter objects with random number keys in Es6

March 22, 2023

I have an object with keys and objects which I am trying to see if I can filter out and return only the ones that match the criteria. This is the object.

the random number keys will or could be different.

{
    "0e93e707-e5aa-4d2b-91ab-a8dec97af344": {
        "Id": "0e93e707-e5aa-4d2b-91ab-a8dec97af344",
        "ExternalSecurityListId": null,
        "CreatorId": "557fa8b2-59db-430d-9595-cd17884c9151",
        "Name": "Chris",
        "PartnerName": null,
        "Type": "Watch",
        "CostBasis": 0,
        "Processing": false,
        "NotificationSettings": {
            "SourceId": "0e93e707-e5aa-4d2b-91ab-a8dec97af344",
            "SourceType": "SecurityList",
            "ChannelTypes": null,
            "NotificationFilters": []
        },
        "Owner": null,
        "SharingStatus": "None",
        "CreatedDate": "2023-02-01T20:31:21.848Z",
        "ModifiedDate": "2023-02-10T17:12:21.053Z",
        "IsGroup": false,
        "UnderlyingSecurityListIds": [],
        "MaturingSoon": false
    },
    "ed89d5a3-464b-4bd7-b9bb-e42ee87f6520": {
        "Id": "ed89d5a3-464b-4bd7-b9bb-e42ee87f6520",
        "ExternalSecurityListId": null,
        "CreatorId": "557fa8b2-59db-430d-9595-cd17884c9151",
        "Name": "Chris Portfolio Two",
        "PartnerName": null,
        "Type": "Portfolio",
        "CostBasis": 100000,
        "Processing": false,
        "NotificationSettings": {
            "SourceId": "ed89d5a3-464b-4bd7-b9bb-e42ee87f6520",
            "SourceType": "SecurityList",
            "ChannelTypes": null,
            "NotificationFilters": []
        },
        "Owner": null,
        "SharingStatus": "None",
        "CreatedDate": "2023-03-20T19:20:02.16Z",
        "ModifiedDate": "2023-03-20T19:20:17.117Z",
        "IsGroup": false,
        "UnderlyingSecurityListIds": [],
        "MaturingSoon": false
    },

}

I tried filterting by key such as this but its not returnig any results.

const allowed = ['Portfolio'];
const filtered = Object.keys(portfoliosData)
  .filter(key => allowed.includes(key))
  .reduce((obj, key) => {
    obj[key] = portfoliosData[key];
    return obj;
  }, {});
const filtered = Object.keys(portfoliosData)
  .filter(key => allowed.includes(key))
  .reduce((obj, key) => {
    obj[key] = portfoliosData[key];
    return obj;
  }, {});

any thoughts or suggestions?

>Solution :

Ok, based on your comments, this is an option to accomplish that:

Object.values(portfoliosData).filter(({Type}) => Type == "Portfolio")

It will list only the values of the topmost object (instead of the keys), and then you iterate on filter with a lambda that captures the property Type and checks if it is equals to the expected value
