The search results are still returning usage examples rather than the actual definition file. Based on the data provided, I don't have access to the core implementation files for useState. The repository data I was given doesn't include the main React hooks source files where useState is defined (typically in packages/react/src/hooks/ or similar).
To find the actual implementation, you would need to look in the core React packages, likely in a file like packages/react/src/hooks/useState.js or in the React reconciler's hooks implementation, but those files are not included in the data I have access to.
FOLLOW_UPS:
- What other hooks are available in React?
- How are hooks implemented internally?
- Where is useEffect defined in the codebase?
