* @example
* Render a Chart component if JS loads, renders a simple FakeChart
* component server-side or if there is no JS. The FakeChart can have only the
* UI without the behavior or be a loading spinner or skeleton.

* ```tsx
* return (
*   <ClientOnly fallback={<FakeChart />}>
*     <Chart />

* Return a boolean indicating if the JS has been hydrated already.
* When doing Server-Side Rendering, the result will always be false.
* When doing Client-Side Rendering, the result will always be false on the
* first render and true from then on. Even if a new component renders it will
* always start with true.
*
* @example
* ```tsx
* // Disable a button that needs JS to work.
* let hydrated = useHydrated()
* return (
*   <button type="button" disabled={!hydrated} onClick={doSomethingCustom}>
*     Click me
*   </button>

* ```
* @returns True if the JS has been hydrated already, false otherwise.
