Core-js is a JavaScript standard library providing polyfills for ECMAScript features, ensuring compatibility across different JavaScript environments. Comparing versions 2.0.3 and 2.0.2, the primary visible difference lies in their release dates: January 11, 2016, for version 2.0.3 and January 3, 2016, for version 2.0.2. While the core functionalities and dependencies remain largely consistent, the updated version likely incorporates bug fixes, performance improvements, and potentially some new polyfills aligned with the evolving JavaScript standards.
Both versions boast a robust set of development dependencies, including tools for testing (Karma, QUnit, promises-aplus-tests), linting (ESLint), bundling (Webpack), and automation (Grunt). The inclusion of LiveScript and its associated Grunt tasks suggests support for transpiling LiveScript code. The testing setup comprehensively covers multiple browsers (Chrome, Firefox, IE, PhantomJS) ensuring cross-browser compatibility for the core-js library itself.
For developers, this signifies that core-js continues to be a reliable choice for standardizing JavaScript functionality. Upgrading from 2.0.2 to 2.0.3 would likely offer a more polished and refined experience, incorporating the latest fixes and potentially minor feature enhancements. Always consult the changelog or release notes for detailed information on specific changes between these versions to understand the full impact of upgrading on your projects. Both versions are released under the MIT license.
