React is fast by default, but as applications grow, performance bottlenecks can appear. In this guide, we'll explore techniques to keep your React apps running smoothly.
Memoization with useMemo and useCallback
Prevent unnecessary re-renders by memoizing expensive calculations and functions. This ensures that components only update when their dependencies change.
Code Splitting
Don't load your entire application at once. Use React.lazy and Suspense to load components only when they are needed. This significantly reduces the initial bundle size.
Virtualization
Rendering large lists can be slow. Libraries like react-window or react-virtualized only render the items currently visible in the viewport, improving performance dramatically.
By implementing these strategies, you can ensure a snappy and responsive user experience for your React applications.
