What are some alternatives to Babel polyfills and core-js?

There are several alternatives you can consider, such as using native JavaScript features, polyfill.io, or even custom polyfills.

Can you explain how polyfill.io works?

Polyfill.io is a service that detects the user's browser and serves only the necessary polyfills based on its capabilities.

Are there any performance implications of using polyfills?

Yes, using polyfills can impact performance, especially if they load unnecessary features for modern browsers. It's best to use them selectively.

What about using native features instead of polyfills?

Using native features is ideal as it reduces the need for additional code, improving performance and reducing bundle size.

Can you recommend some resources for learning more about this?

Sure! You can check out MDN Web Docs, the JavaScript.info website, and various articles on modern JavaScript features.
