[Typo]: Code example mistake in useMemo page

Summary

There is a mistake in the ChatRoom example code on the useMemo page, specifically in the 'Preventing an Effect from firing too often' section.

Page

https://react.dev/reference/react/useMemo#preventing-an-effect-from-firing-too-often

Details

There are two mistakes in the ChatRoom example under the 'Preventing an Effect from firing too often' section:

1. The line const options = createOptions() suddenly appears in the code without context. It seems like this should be removed.
2. In the comment 'Only changes when createOptions changes', the reference to 'createOptions' should be replaced with 'options object'. This is because options is the actual dependency in the useEffect.

Screenshot of typo:

Abre la página de referencia de React useMemo en la sección “Preventing an Effect from firing too often” e inspecciona el ejemplo de ChatRoom. Confirma la línea sobrante createOptions y el comentario sobre las dependencias; después, verifica que el ejemplo sea autocontenido y que la redacción describa con precisión el objeto de opciones.
