Core-js, a foundational JavaScript standard library, saw a minor version update from 0.1.2 to 0.1.3 in November 2014. Examining the package metadata, the primary difference between the two versions lies in their release dates and associated tarball URLs, indicating that 0.1.3 represents a newer build deployed roughly a day after 0.1.2.
For developers considering using core-js, both versions offer a similar set of features, aimed at providing polyfills and shims for modern JavaScript functionality in older environments. The devDependencies section reveals the tools used for development and testing, including Grunt for task automation, Karma for cross-browser testing, and LiveScript as a potential alternative JavaScript dialect. The extensive list of Karma launchers highlights a commitment to ensuring compatibility across various browsers, including Chrome, Firefox, Opera, and Internet Explorer. The use of promises-aplus-tests signals adherence to the Promises/A+ standard, emphasizing robust and reliable promise implementations.
Given the close release dates and identical dependency lists, the update from 0.1.2 to 0.1.3 likely contains bug fixes, performance improvements, or minor code changes within the core library. While a detailed changelog would provide more specifics, developers should generally prefer the latest version (0.1.3) to benefit from any potential improvements and ensure they're using the most up-to-date and stable code base. Core-js helps ensure a consistent coding experience by providing comprehensive cross-browser support for the latest Javascript features.
