Скачать или смотреть React Tips I Wish I Knew Earlier

I’ve seen devs make these same mistakes. Avoid them now with these React pro tips.

1. Think in Components
Not Pages Break UI into small, reusable, testable components. Avoid monolithic components.
Bad: A Dashboard component handling state, layout, and logic for all widgets.
Good: Dashboard having sub components StatsPanel, Chart, Notifications.

2. Use useEffect with care
Avoid running unnecessary logic; always set proper dependency arrays.

3. Memoize when needed
Use useMemo / useCallback to prevent unnecessary re-renders. Use when components lag or re-render deeply nested children.

4. Don’t overuse Context API
It's tempting but can lead to performance issues. Prefer props or local state. Use Redux/Zustand/Jotai when app-wide state is truly required.

5. Follow a design system
Stick to a component library (MUI, Chakra, custom) to ensure consistency. Build a Button once. Don’t recreate it in 10 files.
