React.memo is an underrated tool. It tells React to re-render a component only when its props change — saving time and improving performance.
You should consider using it when:
A component renders large lists
A component receives props that rarely change
You notice repeated unnecessary re-renders in dev tools
The component contains expensive UI logic
It’s especially powerful in Next.js dashboards, tables, lists, and reusable UI components.
Simply wrap your component:
export default React.memo(MyComponent);
This small change can noticeably improve perceived speed in real apps.
