Question 1

How do I include only the fetch polyfill from this project?

Accepted Answer

You can directly download the fetch.js file from the repository or use a CDN link for that specific script. The modular organization allows selective inclusion to avoid loading unnecessary polyfills.

Question 2

Is polyfill better than core-js for JavaScript polyfills?

Accepted Answer

Polyfill focuses more on web platform APIs (HTML, DOM, Fetch) while core-js is centered on ECMAScript language features. Use Polyfill if you need broader web standards support, but core-js for deeper JavaScript language polyfills.

Question 3

Does this polyfill work with Internet Explorer 11?

Accepted Answer

Yes, many polyfills target IE8 and below, so IE11 is supported for most features like querySelector or Fetch. However, check individual polyfills as some might be tailored for even older versions.

Question 4

How to use polyfill with Webpack or modern bundlers?

Accepted Answer

Since it's not packaged as Node modules, you may need to include scripts via CDN or import raw files. The npm package is for distribution only, so integration might require custom configuration or manual script tags.

Question 5

Is the geolocation polyfill accurate?

Accepted Answer

It relies on freegeoip.net, an external service, which may not be as precise as native APIs and depends on network availability, so accuracy and reliability can be limited compared to browser-based geolocation.

Question 6

What's the difference between web.js and polyfill.js bundles?

Accepted Answer

web.js includes common Web polyfills (HTML, DOM, Fetch, etc.) and assumes ES2015 support, while polyfill.js adds ES5 through ES2017 polyfills for broader compatibility with older JavaScript environments.

Question 7

How do I update when new browser versions are released?

Accepted Answer

Monitor GitHub releases for updates, but be cautious with experimental features as they might change. Test thoroughly after updates, especially if using polyfills for unstable or proposed standards.
