About core-js
core-js is a library that provides the most polyfills for missing JavaScript built-in methods and ECMAScript features across different environments, making it easier to write modern JavaScript code that works in older browsers and environments. It offers comprehensive coverage of the ECMAScript specification, helping to bridge the gap between browser support and the latest JavaScript features.
