# I will Fix React.js bug or debug JavaScript error

I will debug and fix one React.js component or JavaScript error in your web application. This service includes root cause analysis, code correction, and basic testing to confirm the issue is resolved.

I specialize in identifying and resolving frontend issues quickly and cleanly. Upon receiving your order, I will first reproduce the error in my local development environment to understand its root cause. Once identified, I will apply the appropriate fix — whether it involves correcting state management, fixing hook dependencies, resolving prop drilling issues, or addressing console errors such as TypeError, ReferenceError, or undefined variables.

After the fix is applied, I will test the affected component or feature to ensure the error no longer appears and that existing functionality remains intact. You will receive the corrected code file with changes clearly indicated, along with a brief explanation of what caused the bug and how it was resolved.

This service is intended for one specific, well-defined issue. If your bug requires more than 60 minutes of work, I will notify you before proceeding and provide a custom quote for the additional work — you will never be charged extra without your prior approval. I work with React 16+ and both JavaScript and TypeScript codebases. Delivery within 24 hours. One revision is included if the fix does not fully resolve your reported issue.
