/**
 * Track whether a component is current mounted. Generally less preferable than

 * but helpful in cases where that isn't feasible, such as a `Promise` resolution.
 *
 * @returns a function that returns the current isMounted state of the component
 *
 * ```ts
 * const [data, setData] = useState(null)
 * const isMounted = useMounted()
 *
 * useEffect(() => {
 *   fetchdata().then((newData) => {
 *      if (isMounted()) {
