What are some effective code-splitting techniques in React?

Code-splitting in React allows you to split your code into smaller chunks, which can be loaded on demand. This improves performance. Common techniques include using React.lazy and Suspense, dynamic imports, and libraries like Loadable Components.

Can you explain how React.lazy works?

Sure! React.lazy allows you to define a component that is loaded dynamically. You wrap your component with React.lazy and it returns a new component that loads the original component only when it is rendered.

What is the role of Suspense in code-splitting?

Suspense is used alongside React.lazy to handle the loading state of the lazy-loaded component. It allows you to specify a fallback UI while the component is being loaded.

Are there any performance considerations I should be aware of?

Yes, while code-splitting can improve load times, over-splitting can lead to too many requests, which may negatively impact performance. It's essential to find a balance.
