A systematic approach to debugging is presented through a real-world example of fixing a scroll jitter bug in a React Router application. The methodology emphasizes creating reliable reproduction cases, narrowing them down incrementally, and maintaining discipline by only committing changes that preserve the bug. The process involves trading complex repros for simpler ones, ensuring each simplified version still captures the original issue, and systematically removing code until the root cause emerges. The bug turned out to be an outdated React Router version where ScrollRestoration triggered on revalidation instead of route changes.
