What is React Suspense and how does it help with code splitting?

React Suspense is a feature that allows you to defer rendering part of your component tree until some condition is met, like data loading. It works well with code splitting by allowing you to load components only when they are needed.

Can you explain how to implement code splitting with React Suspense?

Sure! You can use React.lazy to dynamically import components. Wrap the lazy-loaded component in a Suspense component, providing a fallback UI while the component is loading.

What are some best practices for using React Suspense?

Some best practices include using it for data fetching, keeping your fallback UI simple, and ensuring that your components are small and focused.

Are there any limitations to using React Suspense?

Yes, there are some limitations, such as it not being able to handle errors in loading components directly. You may need to implement error boundaries for that.
