How to change nested field?

Question

JavaScript

Good afternoon!
There is such a data structure

const data = [
 {
  "id": 000,
  "content": "test0",
  "postedAt": 1581515871,
  "answers": [
    {
      "id": 001,
      "content": "test1",
      "postedAt": 1624960660,
      "answers": []
    }
  ]
}
]

And you need to get exactly the same structure at the output, but with a changed field postedAt
at all levels of nesting!

const filteredFirstMessage = useMemo(
        () => ([{
            ...data,
            postedAt: `${format(new Date(data.postedAt * 1000)}`,
        }]),
        [data],
    );

Such an entry works only for 1 nesting level, without taking into account in the arrayanswers

Answer 1

1. Write a loop that iterates through some array of objects and passes each object to a conditional functionchangePostedAt
   
2. The function changePostedAtchanges the field postedAt. It then finds the array in answersand for each object in that array calls changePostedAt.
