Core-js is a JavaScript standard library, providing polyfills for modern ECMAScript features. Versions 3.8.3 and 3.8.2, both MIT-licensed, share the same source repository on GitHub and funding model via Open Collective, ensuring a consistently maintained and community-supported resource for developers. Examining the differences between these releases highlights the iterative improvements within the core-js ecosystem.
While both versions feature a substantial collection of polyfills (1754 files packed through a tarball), the unpacked size of version 3.8.3 is slightly larger at 685,080 bytes, compared to 3.8.2's 684,764 bytes. This indicates that version 3.8.3 incorporates some new additions, modifications or improvements compared to the previous one. Considering the library's role in providing crucial polyfills, this suggests enhancements to existing features or the introduction of new functionality to align with the latest ECMAScript standards.
Developers leveraging core-js to ensure compatibility across various JavaScript environments will find that upgrading from 3.8.2 to 3.8.3 provides access to the newest standard library fixes. These often include bug fixes that increase code stability but also implementation of new features. While the description does not specify the implemented features of this version, one can expect that is is due a minor version upgrade some small modifications and fixes are there. This is really important for developers who deal with javascript compatibility across old devices. With this library they can use modern JS with all devices.
