[Suggestion]: How to avoid null checks when initializing useRef later

Summary

The example is very bad.

Details

The solution how to avoid this pitfall doesn't seem very robust. If for any reason you wanted to instantiate to VideoPlayer but you want your ref to generally be of type VideoPlayer | null you will never be able to put a null in there.

A more robust way actually seems to leverage useState via:

const [playerRef] = useState(()=>({current:new VideoPlayer()}))

While investigating this issue i've concluded that people in general misunderstand what useRef is, going to the extremes of thinking it's "just for dom elements". playerRef in this snipper is exactly MutableRefObject<VideoPlayer> and this approach doesn't involve all kinds of acrobatics, like lying to a type checker, checks inside the render body etc.

Lee la documentación de useRef en la sección enlazada “avoiding recreating the ref contents” y revisa el ejemplo actual y sus supuestos de tipado indicados. Compara el enfoque propuesto con useState con las indicaciones existentes y, después, actualiza el ejemplo o la explicación para que queden claros el tipo de ref previsto, el comportamiento de null y las ventajas y desventajas de la inicialización.
