Learn advanced techniques and best practices for building high-performance React applications.
React is fast by default, but as applications grow, performance bottlenecks can emerge. Here are some strategies to keep your React apps running smoothly.
Memoization
Use React.memo, useMemo, and useCallback to prevent unnecessary re-renders. However, be careful not to overuse them, as they come with their own overhead.
Code Splitting
Break your application into smaller chunks using React.lazy and Suspense. This allows you to load only the code that is needed for the current view, significantly reducing initial load times.
Virtualization
When rendering large lists of data, use virtualization libraries like react-window or react-virtualized to render only the items that are currently visible in the viewport.
