Core-js versions 0.4.0 and 0.4.1 represent incremental updates to this standard library, intended to provide comprehensive JavaScript language support. Both versions share the same core purpose: offering modern JavaScript features and polyfills for older environments, ensuring cross-browser compatibility and enabling developers to leverage the latest ES features regardless of the target platform.
A quick look reveals identical development dependencies, including tools like Grunt for task automation, Karma for testing, and LiveScript for code generation. This indicates a consistent development and testing environment between the two releases. The repository URL remains constant, pointing to the core-js GitHub repository, reinforcing that both versions stem from the same codebase and project.
The key difference lies in the 'version' field and 'releaseDate'. Version 0.4.1 was released on January 5th, 2015, a day after version 0.4.0, released on January 4th, 2015. Given the minor version bump (0.4.0 to 0.4.1), it's highly probable that version 0.4.1 includes bug fixes, minor feature enhancements, or performance improvements over its predecessor. For developers using core-js, upgrading from 0.4.0 to 0.4.1 is recommended to benefit from these potential improvements. These incremental releases help ensure that a developer is working with the most stable and up-to-date polyfills and standard library features available. The dist.tarball also differs, pointing to the specific archive for each version on the npm registry.
