Copy array of objects and make changes without modifying original array

Question

I have an array of objects. I would like to deep copy the array of objects and make some changes to each object. I want to do this without modifying the original array or or

Answer 1

Yes that looks good. You could also perform the modification when you are cloning, in order to avoid mapping over the array twice.

const users2 = users.map((u) => {
    const copiedUser = Object.assign({}, u);
    copiedUser.approved = true;
    return copiedUser;
});
