React gives us powerful optimization tools… But many devs use them randomly. Here’s the simple rule: 🟠 useEffect → for side effects (API calls, subscriptions, DOM work) 🔵 useMemo → to memoize computed values 🟢 useCallback → to memoize functions If you use useEffect for calculations… you’re misusing it. If you pass new functions every render… you cause re-renders. The goal is NOT to use all 3 hooks. The goal is to use the right hook for the right job.
