Core-js is a widely used JavaScript standard library, that provides polyfills for modern ECMAScript features, ensuring compatibility across different browsers and environments. Examining versions 3.1.2 and 3.1.1, subtle yet important changes emerge. Both versions share the same licensing (MIT) and repository details, indicating a continuation of the project's open-source nature and development philosophy. They also have a similar file count of 1593.
However, a key difference lies in the unpackedSize, where version 3.1.2 has a slightly larger footprint at 540522 bytes compared to 3.1.1's 540467 bytes. While seemingly small, this increase potentially signals the addition of new polyfills or minor updates to existing ones. Developers should consider this size increase if bundle size is a critical concern. The release dates also highlight the recency of these versions, with 3.1.2 released just a day after 3.1.1.
For developers using core-js, this implies a rapid development cycle focused on incremental improvements. Upgrading from 3.1.1 to 3.1.2 likely delivers very small improvement, but developers should review the changelog for a comprehensive understanding of specifically added or modified features. Always test in production environment to make sure there is nothing breaking.
