Step: Rename keys: {new: .old}

To rename, give the key explicitly and a filter for the value: {new: .old}.

{carMake: .make, carModel: .model}

Your turn: rename firstName→name and lastName→surname.

Input:

{
  "firstName": "Charles",
  "lastName": "Doe",
  "location": {
    "city": "San Francisco",
    "postal-code": "94103"
  }
}

jq Expression

Expected:

{
  "name": "Charles",
  "surname": "Doe"
}
