What does this code mean?

Question

const [votes, setVotes] = useState({
0: 0,
1: 0,
2: 0,
3: 0,
4: 0,
5: 0,
});

const mostVoted = Object.keys(votes).sort((a, b) => votes[b] - votes[a])[0];

I don't understand what will be stored in mostVoted constant.
Who can explain me what is the logic of this function?
Thanks

Elena , first you get the keys => 0, 1, 2, 3, 4, 5; then you sort them in reverse order (5, 4, 3, 2, 1, 0), finally you get the first key in the sorting sequence => 5.
