About core-js

core-js is a modular standard library for JavaScript that provides polyfills for ECMAScript features, including newer syntax and built-in objects not yet supported in all browsers. It is one of the most widely downloaded packages in the JavaScript ecosystem and is commonly used under the hood by Babel and other transpilation tools.

Maintained primarily by Denis Pushkarev, core-js enables developers to use modern JavaScript features while maintaining compatibility with older browsers and environments. It is included as a dependency in countless frameworks, build tools, and applications, making it one of the most ubiquitous JavaScript libraries on the web, even when not explicitly listed as a direct dependency.
