How does code splitting affect performance?

What is code splitting and how does it improve performance?

Code splitting is a technique that allows you to split your code into smaller chunks, which can be loaded on demand. This improves performance by reducing the initial load time of your application, as users only download the code they need.

Can you explain how it works in a React application?

In React, code splitting can be achieved using dynamic imports and React.lazy. This allows components to be loaded only when they are needed, rather than all at once.

Are there any downsides to using code splitting?

Yes, while code splitting can improve load times, it may introduce additional complexity and can lead to a slight delay when loading chunks for the first time.

How can I implement code splitting in my project?

You can implement code splitting using tools like Webpack or by utilizing React's built-in features like React.lazy and Suspense.
