Core-js versions 0.5.0 and 0.5.1 are incremental releases of a standard library polyfill, primarily aimed at providing modern JavaScript functionality in older environments. Examining the differences between these versions reveals that the core functionality and intended use remain largely consistent. Both versions maintain the same core description as a "Standard library," utilize identical development dependencies (including tools like Grunt, Karma, and LiveScript for building, testing, and transpiling), and share the same MIT license and repository information.
The key distinction lies in the releaseDate. Version 0.5.1 was released on February 8, 2015, a day after version 0.5.0, which was released on February 7, 2015. This small time gap strongly suggests that version 0.5.1 is a patch release addressing minor bugs or refinements present in 0.5.0.
For developers, this means that upgrading from 0.5.0 to 0.5.1 should be a safe and recommended practice to benefit from any bug fixes or minor improvements. Users implementing core-js to ensure compatibility with modern JavaScript features across various browsers and JavaScript engines should prioritize using the latest version to leverage these refinements.
