Deleting properties from an object of objects

I am trying to remove a number of properties from an object of objects I've found a lot of questions on stack overflow about doing this for array but I can't seem to figure out a clean way of going about doing this for my purposes.

My data looks like this:

{ 
emr: {ID: "user-1504966781-340782", languageDesc: "English", orgId: 1504966781,…}
pcc: {ID: "user-1504966781-340782", languageDesc: "English", orgId: 1504966781,…}
}

The goal here is to remove let's say languageDesc, and orgID from the emr and pcc objects while keeping the rest of the object intact. The issue with the way I'm implementing this change is I am trying to use the delete operator which works but I have to delete 10 items from the emr and pcc data separately so my code does not look good. Can anyone show me a better way to go about doing this?

this is what my codes looking like right now:

const pcc = result.pcc;
const emr = result.emr;

delete pcc["MedicalPractices"];
delete pcc["CovidZone"];
delete pcc["picturePath"];
delete pcc["DoseSpotID"];
delete pcc["consentStatus"];
delete pcc["consentStatusLastUpdate"];
delete pcc["consentStatusUpdatedBy"];
delete pcc["consentStatusChangeReason"];
delete pcc["syncStatus"];
delete emr["MedicalPractices"];
delete emr["CovidZone"];
delete emr["picturePath"];
delete emr["DoseSpotID"];
delete emr["consentStatus"];
delete emr["consentStatusLastUpdate"];
delete emr["consentStatusUpdatedBy"];
delete emr["consentStatusChangeReason"];
delete emr["syncStatus"];

console.log(pcc);
this.setState({ pccData: pcc });
this.setState({ emrData: emr });

Creating an array of items you want to delete and then just looping for each item. Finally deleting those mentioned in arrays !

Deleting separately

let delete_items_pcc = ["MedicalPractices", "CovidZone", "picturePath" ....]
let delete_items_emr = ["MedicalPractices", "CovidZone", "picturePath" ....]
delete_items_pcc.forEach(item => delete pcc[item])
delete_items_emr.forEach(item => delete emr[item])

Deleting simultaneously

let delete_items = ["MedicalPractices", "CovidZone", "picturePath" ....]
delete_items.forEach(item => {
  delete emr[item]
  delete pcc[item]
})

I'd create two lists, one of the objects you want to delete from and one of the properties you want to delete and iterate over them in a nested loop:

const objects = ["pcc", "emr"];
const props = ["MedicalPractices", "CovidZone", "picturePath", "DoseSpotID", "consentStatus", "consentStatusLastUpdate", "consentStatusUpdatedBy", "consentStatusChangeReason", "syncStatus"];
objects.forEach(o => {
    props.forEach(p => 
        delete result[o][p];
    });
});
