Use the React DevTools Components tab to inspect props and state, the Profiler for performance, the Network tab for API issues, read the console for specific errors, use strategic logs, binary search to narrow the cause, and isolate the bug in a minimal example.
It records a render and shows which components are slow or re-render unnecessarily, and why they re-rendered. This is essential for performance debugging, where guessing does not help.
Use the Network tab. It shows every request, its status, headers, and response. Most API bugs, wrong status, wrong shape, missing headers, can be diagnosed there.
