Core-js is a JavaScript standard library providing polyfills for modern JavaScript features, aiming to ensure compatibility across different browsers and environments. Version 0.2.5, released on December 20, 2014, follows closely after version 0.2.4, released just three days prior on December 17, 2014. Both versions share the same core description as a "Standard library" and rely on an identical set of development dependencies, including Grunt for task automation, Karma for testing, LiveScript for code generation, and various Karma launchers for cross-browser testing.
The consistent dependency list indicates that the changes between these two versions likely focus on bug fixes, performance improvements, or minor feature additions rather than a significant overhaul of the library's core functionality or development tooling. Developers using core-js can likely upgrade from 0.2.4 to 0.2.5 with minimal risk of breaking changes, gaining the benefit of any refinements made in the newer version. Both versions utilize a robust testing framework, ensuring a high level of stability and reliability. The library's repository remains consistent across both versions, pointing to the same GitHub repository, signaling the continued maintenance and development of core-js as a go-to solution for JavaScript compatibility. Developers looking for a reliable set of polyfills to bring modern JavaScript features to older browsers will find both versions suitable, but version 0.2.5 is preferable due to its likely inclusion of recent improvements.
