How to assign an Object Key as an ID value in the Object?-CodePudding

I have an Javascript object object like the following:

    "xx2b": {
        "county": "Baringo",
        "town": "Kabarnet",
        "saccoRegistration": "BO2/08/009",
        "saccoName": "Baringo2"
    },
    "QQDa": {
        "saccoRegistration": "Ba/09/009",
        "town": "Mogotio",
        "county": "Baringo",
        "saccoName": "Baringo1"
    }
}

How do I assign the Object Keys also to be values within the objects?

The expected outcome is as illustrated below:

{
    "xx2b": {
        "id": "xx2b",
        "county": "Baringo",
        "town": "Kabarnet",
        "saccoRegistration": "BO2/08/009",
        "saccoName": "Baringo2"
    },
    "QQDa": {
        "id":"QQDa",
        "saccoRegistration": "Ba/09/009",
        "town": "Mogotio",
        "county": "Baringo",
        "saccoName": "Baringo1"
    }
}

CodePudding user response：

You can use forEach to iterate the object keys and add a new property to each nested object:

const data = {
    "xx2b": {
        "county": "Baringo",
        "town": "Kabarnet",
        "saccoRegistration": "BO2/08/009",
        "saccoName": "Baringo2"
    },
    "QQDa": {
        "saccoRegistration": "Ba/09/009",
        "town": "Mogotio",
        "county": "Baringo",
        "saccoName": "Baringo1"
    }
}

Object.keys(data).forEach(k => data[k].id = k)

console.log(data)
