Deleting properties from nested objects-CodePudding

Having an object like this one:

{
    "status": "OK",
    "initialState": {
        "id": "dc3c89d27fd2aae78287c53f952c3b6a",
        "product": {
            "productName": "Cars",
            "description": null
        },
        "models": {
            "Toyota Avensis": {
                "id": "Toyota Avensis",
                "parent": "sedan",
                "required": false,
                "disabled": true,
                "visibility": true,
                "error": false
            },
            "Toyota Corolla": {
                "id": "Toyota Corolla",
                "parent": "sedan",
                "required": true,
                "disabled": false,
                "visibility": true,
                "error": false
            },
            "Ford Focus": {
                "id": "Ford Focus",
                "parent": "sedan",
                "required": false,
                "disabled": true,
                "visibility": true,
                "error": false
            },
            "Ford Mondeo": {
                "id": "Ford Mondeo",
                "parent": "sedan",
                "required": false,
                "disabled": true,
                "visibility": true,
                "error": false
            }
        },
        "userId": "user1",
        "status": 1
    }
}

I was trying to delete properties like disabled and error from the initialState.models objects.

My last attempt was unsuccessful though. What I tried was something like (assuming that the object above is stored as const myObject):

Object.entries(myObject.initialState.models).forEach(([key, value]) => {
    Object.entries(value).forEach(([subKey, subValue]) => {
        if (subKey === 'disabled') {
            delete myObject.initialState.models[value.disabled];
        }
    });
});

But that way, nothing was deleted. What should be done to remove properties like disabled and error uncoditionally?

Instead of iterating through the keys and values of each model, you can directly delete the disabled and error keys from each model:

Object.entries(myObject.initialState.models).forEach(([key, value]) => {
    delete value.disabled;
    delete value.error;
});

The above answer is the best way to handle this. What mistake you did is following

Object.entries(obj.initialState.models).forEach(([key, value]) => {
Object.entries(value).forEach(([subKey, subValue]) => {
    if (subKey === 'disabled') {
        delete obj.initialState.models[key].disabled; // Here you did mistake
        delete obj.initialState.models[key].error;
    }
});});
