Babel-runtime versions 4.7.0 and 4.7.1 represent incremental updates to the Babel's self-contained runtime library. Both versions share the same fundamental purpose: providing the necessary polyfills and helper functions for running Babel-transformed code in environments that lack native support for newer JavaScript features introduced in ECMAScript specifications. This ensures broader compatibility across different browsers and Node.js versions. Both packages are authored by Sebastian McKenzie and the source code resides within the Babel project on GitHub, highlighting their integral role in the Babel ecosystem.
However, 4.7.1 represents a patch release addressing any immediate fixes or refinements identified after the 4.7.0 release. Developers looking to adopt Babel-runtime should prioritize version 4.7.1. Even though the changes between them will probably be minimal, applying patch updates is important to benefit from the latest improvements and bug fixes. Crucially, by including babel-runtime as a project dependency, developers avoid having to manually manage and update the runtime environment, simplifying the development and deployment process. Moreover, this approach can reduce code duplication, as the necessary runtime helpers are included only once rather than repeatedly injected into each compiled module. Considering that the two releases' dates were on the same day, the 4.7.1 version represents a really small adjustment of the code, probably fixing a small unnoticed bug or a small typo.
