Core-js, a foundational JavaScript library providing standardized implementations of ECMAScript features, released version 3.19.2 following version 3.19.1. Both versions, licensed under MIT, continue to offer a robust and comprehensive collection of polyfills, shims, and proposals designed to ensure cross-browser compatibility and access to the latest JavaScript features in older environments. Developers leveraging core-js benefit from a consistent and predictable JavaScript runtime, regardless of the user's browser.
While both versions share the same core objective, a closer look reveals subtle differences. Version 3.19.2, released on November 29, 2021, incorporates a minor update. It encompasses 1892 files in the packaged tarball, slightly more than the 1891 files of version 3.19.1, released on November 2, 2021. The unpacked size of version 3.19.2 is also marginally larger, at 820932 bytes, compared to 817992 bytes in the previous version. This suggests that version 3.19.2 likely includes bug fixes, performance enhancements, or minor feature additions compared to its predecessor. Developers should consult the official core-js changelog on GitHub to understand the specific changes introduced. The library is openly funded via Open Collective, and contribution to the further development is welcome. When upgrading, developers are encouraged to review these changes to ensure compatibility with their existing code and take advantage of any improvements.
