Research direction
Open the React useMemo reference page at the “Preventing an Effect from firing too often” section and inspect the ChatRoom example. Confirm the stray createOptions line and the dependency comment, then verify the example is self-contained and the wording accurately describes the options object.

Details
There are two mistakes in the ChatRoom example under the 'Preventing an Effect from firing too often' section:
- The line
const options = createOptions()suddenly appears in the code without context. It seems like this should be removed. - 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.
