What are the best practices for code splitting in web development?

Code splitting is a technique to split your code into smaller chunks, which can be loaded on demand. Best practices include using dynamic imports, leveraging libraries like React.lazy, and analyzing bundle sizes with tools like Webpack.

How do I implement dynamic imports in my project?

You can implement dynamic imports using the import() function. For example, instead of importing a component at the top, you can do it inside a function or a React component's lifecycle method.

What tools can help me analyze my bundle sizes?

Tools like Webpack Bundle Analyzer, Source Map Explorer, and Lighthouse can help you analyze and visualize your bundle sizes effectively.

Are there any performance implications I should be aware of?

Yes, while code splitting improves load times, excessive splitting can lead to too many network requests. It's essential to find a balance.
