We benchmarked five common performance anti-patterns and walked through practical fixes using React DevTools, useMemo, and the new use() hook.
React performance problems are almost always the result of a small set of well-known anti-patterns: unnecessary re-renders, missing keys, expensive computations in render, and waterfall data fetching. This article walks through each one with real profiler traces and concrete fixes.
The Profiler is Your Best Friend
Before optimising anything, open React DevTools Profiler and record an interaction. Find the components with the widest bars. Those are your targets — everything else is premature optimisation.
