Passing new object/array/function references on every render can cause child components to re-renderโeven when nothing actually changed.

- Memoize functions with "useCallback"

Your app works perfectly locally, then suddenly breaks in production.
Before blaming the code, check:
๐น Environment variables
๐น Node.js versions
๐น Database connection
๐น API URLs
๐น CORS configuration
๐น Production build settings
Local success โ production readiness.
Always test your application in an environment as close to production as possible.
