Optional chaning for javascript object destructuring-CodePudding

I have an object, and i trying to access the object properties using destructuring. The problem is there are cases where state itself is undefined. Hence, i wanted to add optional chaining. However, i am stuck...

const {state: {one, two, three, four}} = useLocation()

My solution:

const {state?: {one, two, three, four}} = useLocation()

Problem: How can i add optional chaining for such syntax?

Otherwise the solution would be

    useEffect(() => {
    if (!state) {
      setUserBirth(state?.userBirth);
      setUserEmail(state?.userEmail);
      setUserTel(state?.userTel);
      setUserName(state?.userName);
      setType(state?.type);
    }
  }, [state]);

But im wondering if i could directly apply optional chaining onto object destructuring

CodePudding user response：

You can do something like this

const {state: {one, two, three, four} = {}} = useLocation()

This will at least prevent the error when the state is undefined
