About

Babel is a JavaScript compiler mainly used to convert ECMAScript 2015+ (ES6) code into an older JavaScript (ES5) version to maximize browser compatibility.

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.
