React18 : How React 18 Improves Application Performance in Detail

Conclusion

In summary, React 18's latest features improve performance in many ways.

• With Concurrent React, the rendering process can be paused and resumed later or even abandoned. This means the UI can respond immediately to user input even if a large rendering task is in progress.
• The Transitions API allows for smoother transitions during data fetches or screen changes without blocking user input.
• React Server Components lets developers build components that work on both the server and client, combining the interactivity of client-side apps with the performance of traditional server rendering without the cost of hydration.
• The extended Suspense functionality improves loading performance by allowing parts of the application to render before others that may take longer to fetch data.
