 * Making refs stateful opens up the possibility of using the element the ref is pointing to as a dependency for a `useEffect` call
 *
 * @example
 * Here's a simple example
 * ```ts
 *  // At the top most level of the functional component
 *  const [inputElement, setInputRef] = useStateRef<HTMLInputElement | null>(null);
 *
 *  // Inside the JSX
 *  <input type = "text" ref = {setInputRef} />
 * ```
