What are advanced code splitting techniques in JavaScript?

Advanced code splitting techniques in JavaScript involve breaking your code into smaller chunks that can be loaded on demand, improving performance. Techniques include dynamic imports, route-based splitting, and using libraries like React Loadable.

Can you explain dynamic imports and how they work?

Dynamic imports allow you to load modules asynchronously using the import() function. This means you can load a module only when it's needed, reducing the initial load time of your application.

What is route-based code splitting?

Route-based code splitting involves splitting your code based on the routes in your application. Each route can load its own chunk of code, which is only fetched when the user navigates to that route.

Are there any tools or libraries that can help with code splitting?

Yes, tools like Webpack and libraries like React Loadable or React.lazy can help implement code splitting effectively in your applications.
