Core-js is a widely used JavaScript standard library providing polyfills for modern ECMAScript features, ensuring compatibility across different JavaScript environments. Version 3.4.4 introduces subtle changes compared to its predecessor, version 3.4.3, reflecting ongoing efforts to refine and optimize the library. Both versions maintain the same license (MIT) and repository, indicating a consistent development approach. Both also link to the same Open Collective funding page .
A key difference lies in the unpackedSize. Version 3.4.4 weighs in at 647606 bytes when unpacked, a slight increase from 3.4.3's 647038 bytes. This suggests the addition of new features, enhancements to existing polyfills, or minor bug fixes impacting the overall size. Both package has the same fileCount (1682 files), this difference in packed sized confirm what was said before. Developers should investigate the changelog for a detailed breakdown of these changes to assess their impact on specific projects.
The releases are very close on time (less then one day of difference), which suggest that the 3.4.4 release may target some bug in the previous version and might be highly suggested to update. Both versions are good options and very similar, but developers need to evaluate the changes.
