Common Pitfalls to Avoid
- ⚠️Simply stating the definition without providing context or common use cases for each code.
- ⚠️Confusing '401 Unauthorized' (authentication required/failed) with '403 Forbidden' (authenticated but no permission).
- ⚠️Not clearly distinguishing between client-side errors (4xx) and server-side errors (5xx).
- ⚠️Failing to mention the importance of 301 for SEO and permanent URL changes.
- ⚠️Giving overly simplistic explanations, such as just '200: OK', without elaborating on its significance in a request-response cycle.
