What are the best practices for using concurrent mode in React?
Concurrent mode in React allows for more responsive user interfaces. Best practices include using Suspense for data fetching, optimizing rendering with useTransition, and ensuring compatibility with existing components.
Can you explain how Suspense works in concurrent mode?
Suspense lets you pause rendering while waiting for something, like data. It shows a fallback UI until the data is ready, improving user experience.
What should I avoid when using concurrent mode?
Avoid blocking the main thread with heavy computations. Also, be cautious with state updates that can lead to race conditions.
How does concurrent mode affect performance?
It improves performance by allowing React to work on multiple tasks simultaneously, leading to smoother interactions and faster load times.
Are there any tools to help with debugging in concurrent mode?
Yes, React DevTools has features specifically for concurrent mode, allowing you to inspect the state and performance of your components.
