A set of utility and general-purpose React hooks.

/**
 * A convenience hook around `useState` designed to be paired with
 * the component [callback ref](https://reactjs.org/docs/refs-and-the-dom.html#callback-refs) api.
 * Callback refs are useful over `useRef()` when you need to respond to the ref being set
 * instead of lazily accessing it in an effect.
 *
 * ```ts
 * const [element, attachRef] = useCallbackRef<HTMLDivElement>()
 *
 * useEffect(() => {
 *   if (!element) return
 *
 *   const calendar = new FullCalendar.Calendar(element)
 *
 *   return () => {
 *     calendar.destroy()
 *   }
 * }, [element])
 *
 * return <div ref={attachRef} />
 * ```
 *
