About

Polyfill.io is an open-source JavaScript library that provides modern web API features to older browsers that do not natively support them.

After a supply chain attack in 2024 involving its cdn.polyfill.io domain, the service was discontinued and is now safely mirrored and maintained by Cloudflare under independent management.

Select2 is a jQuery based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results.
