How do I troubleshoot polyfill issues in my web application?

To troubleshoot polyfill issues, first check if the polyfills are correctly included in your project. Are you using a bundler?

Yes, I'm using Webpack. What should I look for in the configuration?

Ensure that the polyfills are listed in the entry point of your Webpack configuration. Also, check for any errors in the console.

I see some errors related to missing features. What can I do about that?

You might need to update your polyfills or include additional ones for the missing features. Can you specify which features are causing issues?

It's mainly for Promise and Fetch APIs. What polyfills do I need?

For Promise, you can use 'promise-polyfill', and for Fetch, 'whatwg-fetch' is a good choice. Make sure to import them in your project.
