Babel-polyfill versions 6.22.0 and 6.20.0, designed to provide comprehensive ES2015+ polyfills, share a common goal: enabling developers to write modern JavaScript code that runs smoothly across diverse environments, even those lacking native support for newer features. Both versions rely on core-js, regenerator-runtime, and babel-runtime to achieve this compatibility. The key difference between the two versions lies in their specific dependencies on babel-runtime. Version 6.22.0 depends on babel-runtime version ^6.22.0, while the older 6.20.0 relies on ^6.20.0. This difference implies potential bug fixes, performance improvements, or new features introduced within the babel-runtime package between these versions. For developers, this means upgrading to babel-polyfill 6.22.0 brings access to the latest runtime enhancements. The update ensures compatibility with recent Babel transformations and potentially resolves issues encountered in earlier versions. Considering the MIT license, developers gain the freedom to use and modify the polyfill as needed. Always check the changelog for babel-runtime to understand the specific changes implemented and whether those changes address any concerns or provide desired functionalities for your project. The release date difference, roughly a month and a half, suggests a fairly regular update cycle aiming to keep pace with evolving JavaScript standards and to address any reported issues.
