Table not re -rendering after sorting useState object

const [members, setMembers] = useState([]);
  useEffect(() => {
    getMembers();
  }, []);

  const sortByName = () => {
    const sorted = members.sort((a, b) => {
      if (a.name < b.name) {
        return -1;
      }
      if (a.name > b.name) {
        return 1;
      }
      return 0;
    }
    );
    setMembers(sorted)
  }


{members.map((person) => {
return (
<Member key={person.member_id} person={person}/>
)})}

The table is not re-rendered with the sorted data after the sortByName function is called, console logging the member variable gives proper sorted data, but the table still displays the old data

I think sort method doesnt return a new array. So maybe u need to try :

setMembers([...sorted])
