Core-JS version 3.20.0 introduces notable enhancements over its predecessor, version 3.19.3, offering developers an updated and expanded standard library. While both versions maintain the same core functionality and licensing under MIT, significant differences emerge in terms of size, content, and release date. Released on December 15, 2021, version 3.20.0 arrives approximately nine days after version 3.19.3, which was published on December 6, 2021.
The newer version showcases a substantial increase in both file count and unpacked size. Version 3.20.0 comprises 2380 files with an unpacked size of 924,688 bytes, compared to version 3.19.3's 1892 files and 821,690 bytes. This increase suggests the addition of new features, polyfills, or refinements to existing functionalities. Developers adopting version 3.20.0 can benefit from an expanded set of tools and potentially improved compatibility with modern JavaScript standards. Core-js remains a valuable asset for ensuring cross-browser compatibility and leveraging cutting-edge ECMAScript features in older environments by providing the necessary polyfills. Users should consider updating to leverage the latest fixes and features, noting the increase in package size. The funding model remains consistent, using Open Collective.
