Core-js, a foundational standard library for JavaScript, saw a notable update between versions 2.3.0 and 2.4.0. Both versions provide essential polyfills, enabling developers to utilize modern JavaScript features in older environments. Examining the *devDependencies*, reveals key shifts in the testing and build pipeline that impacted core-js development.
Version 2.4.0 updated *eslint* from 2.8.x to 2.9.x, suggesting minor enhancements in code linting and style enforcement. Significant upgrades are present in several *karma-* related packages: *grunt-karma* went from 0.12.x to 1.0.x; *karma-qunit* from 0.1.x to 1.0.x; *karma-ie-launcher* from 0.2.x to 1.0.x; *karma-chrome-launcher* from 0.2.x to 1.0.x; and *karma-firefox-launcher* from 0.1.x to 1.0.x. This denotes a substantial refresh of the testing framework, moving towards newer versions of Karma and its related launchers implying improvements in the testing process across various browsers, potentially contributing to more robust cross-browser compatibility testing. These changes generally indicate that version 2.4.0 might have included updates to improve code quality and ensure more reliable functionality across different JavaScript engines and browsers.
