Babel-polyfill versions 6.6.0 and 6.5.0 offer developers a way to bring modern JavaScript features to older browsers and environments. Both versions aim to emulate missing features, enabling broader compatibility for web applications. Examining the differences reveals key improvements. The most notable change between version 6.6.0 and 6.5.0 lies in its dependency on core-js. Version 6.6.0 upgrades core-js to version ^2.1.0, while version 6.5.0 relies on ^1.0.1. This core-js upgrade is important, as it likely incorporates new polyfills and bug fixes, improving support for newer JavaScript features like symbols, promises, and iterators . Both versions, that includes @babel/runtime, and babel-regenerator-runtime are using MIT License. Developers should upgrade to version 6.6.0 from 6.5.0 to benefit from enhanced JavaScript standard compliance and potentially resolve legacy browser compatibility issues that might have been present in older core-js versions. While both versions share the same author and repository, indicating a consistent development approach, using the newer core-js provides peace of mind and reduces the likelihood of encountering compatibility gaps when targeting a diverse range of user environments. Remember to test accordingly to ensure the new polyfills doesn't introduce new issues.
