deleting data from js object

Question

I have a js object from my react app and want to delete a single data. The object is as follows

state = {
  data: []
}

const contactData = {
  Datas: {
    name: "william",
    email: "test@test.com",
    phoneNumber: "07123456",
    addressOne: "street1 ",
    addressTwo: "street2",
    postCode: "hd1 2rd ",
    country: "UK"
  }
};

const DateAdd = {
  ...contactData,
  id: new Date()
};
const immutate = {
  ...state,
  data: state.data.concat(DateAdd)
};

console.log(immutate);

I able to delete all the data with this method but not a single data

const deleteData = immutate.data.filter(own => own.id !== "generated date");

how would I able to delete like name or email only? appreciate for your helps.

You can use filter the same way you use it there but do it on the keys of the object (Object.keys(o).filter..) this wat you can filter out a key like key === “name” — Luciano Semerini, Apr 05 '19 at 13:10

Do you mean delete `name` or `email` from every object in `data`, or just one of them? — Tholle, Apr 05 '19 at 13:12

So you want to remove only one key from your Datas object right? Here is an example of removing only the email.

const { email, ...rest } = immutate.data.Datas

const deleteData = {
  ...immutate,
  data: {
    ...immutate.data,
    Datas: {
      ...immutate.data.Datas,
      ...rest
    }
  }
}
