What is code splitting in Gatsby and how does it work?

Code splitting in Gatsby is a technique that allows you to split your JavaScript code into smaller chunks. This means that only the necessary code for the current page is loaded, improving performance and reducing load times.

Why is code splitting important for web performance?

Code splitting is important because it reduces the amount of JavaScript that needs to be loaded initially. This leads to faster page loads and a better user experience, especially on mobile devices.

How can I implement code splitting in my Gatsby project?

In Gatsby, code splitting is handled automatically by the framework. You can use dynamic imports for components that are not needed immediately, which will create separate bundles for those components.

Can you give me an example of dynamic imports in Gatsby?

Sure! You can use the React.lazy function to dynamically import a component like this: const MyComponent = React.lazy(() => import('./MyComponent')); This will split the code for MyComponent into a separate bundle.
