Your React app doesn't always need more optimization. Sometimes, it just needs fewer re-renders. ⚛️

Your React app doesn't always need more optimization. Sometimes, it just needs fewer re-renders. ⚛️

One thing I've learned while working on frontend experiences is that adding useMemo, useCallback, and React.memo everywhere isn't the same as writing performant React code.

Before optimizing, I focus on a few things:

🔹 Understand the problem first:- Use React DevTools

Profiler to identify unnecessary or expensive renders.

🔹 Keep state close to where it's needed:- Not every state update needs to trigger a large part of the component tree.

🔹 Avoid premature optimization:- Memoization adds complexity and isn't always beneficial.

🔹 Measure before and after:- If there's no meaningful improvement, the optimization might not be worth it.

When you're building experiences like checkout flows, performance isn't just a technical metric. It affects how smoothly people can complete an important task.

My rule of thumb: Measure first. Optimize second. Keep it simple.
