How does a React Router loader know which item to load?

export async function loader({ params }) {
  return getUser(params.id);
}

✓Correct answer: It receives params (and the request) as an argument
2It calls useParams() inside the loader
3It reads a global variable set by the component

Explanation

Loaders run outside components, so hooks aren't available. request.url gives access to search params too.
