What are the performance impacts of using dynamic imports in JavaScript?

Dynamic imports can improve initial load times by splitting code into smaller chunks, loading them only when needed.

Are there any downsides to using dynamic imports?

Yes, while they can enhance performance, they may introduce latency during runtime as modules are fetched on demand.

How do dynamic imports affect bundle size?

Dynamic imports can reduce the initial bundle size since only the necessary code is loaded at startup, optimizing resource usage.

Can you give an example of when to use dynamic imports?

A common use case is loading a library only when a user interacts with a specific feature, like a modal or a chart.

What tools can help analyze the performance of dynamic imports?

Tools like Webpack Bundle Analyzer and Lighthouse can help you assess the impact of dynamic imports on your application's performance.
