How does `useId` help in React forms?

1It generates keys for lists of inputs that change order
2It makes unique, SSR-safe ids for htmlFor and ARIA links
3It stores a user's id so the form can be pre-filled later

Show the answer

Correct answer: It makes unique, SSR-safe ids for htmlFor and ARIA links

Explanation

Reusable components can't hard-code ids, or two instances would clash. Don't use it for list keys.
