What are the best practices for lazy imports in JavaScript?

Lazy imports can improve performance by loading modules only when needed. Here are some best practices: 1. Use dynamic imports with import(). 2. Split your code into smaller chunks. 3. Prioritize critical resources. 4. Monitor loading times.

Can you give an example of using dynamic imports?

Sure! You can use dynamic imports like this: const module = await import('./module.js'); This loads the module only when the code reaches that line.

What are the benefits of lazy loading?

The benefits include reduced initial load time, improved performance, and better user experience, especially for large applications.

Are there any downsides to lazy loading?

Yes, potential downsides include increased complexity in code management and possible delays in loading resources if not handled properly.
