React setState of an object with count

I have an array of integers from 0 to 6 as input I need to return an object with the count of each of those numbers

edition = [6, 6, 6, 1, 1, 2];
const [groupedEdition, setGroupedEdition] = useState([{"0": 0, "1": 0, "2": 0, "3": 0, "4": 0, "5": 0, "6": 0}]);

but I can’t do the function for the set of values

{edition.map((prodotto) => {
    setGroupedEdition({...groupedEdition, XXXX});
})}

I am expecting this

groupedEdition = {"0": 0, "1": 2, "2": 0, "3": 0, "4": 0, "5": 1, "6": 3}

Can you help me? Thank you very much

Answer

You can use reduce()

const edition = [6, 6, 6, 1, 1, 2];
const initialValue = {"0": 0, "1": 0, "2": 0, "3": 0, "4": 0, "5": 0, "6": 0};

const groupedEdition = edition.reduce((acc, item) => {
  acc[item] += 1;
  return acc;
}, initialValue);
console.log(groupedEdition);
