Core-js is a widely-used JavaScript standard library, offering polyfills and shims for modern ECMAScript features, ensuring compatibility across diverse JavaScript environments. Examining versions 3.1.4 and 3.1.3 reveals subtle but potentially important changes for developers. While both maintain the same MIT license, repository, and overall structure, the release dates provide a clear timeline: 3.1.4 arrived on June 15, 2019, succeeding 3.1.3, released on May 27, 2019. The "dist" section sheds light on the package's contents. Version 3.1.4 contains 1592 files and unpacks to 565545 bytes, a slight decrease in the number of files compared to 3.1.3's 1593. Although the file number decreased, the overall unpacked size grew from 559670 bytes, revealing internal modifications and additions or changes to codebase size.
For developers, this suggests that version 3.1.4 likely incorporates bug fixes, performance improvements, or new feature implementations that necessitate more space. Before upgrading, developers should check the changelog between these versions on the core-js GitHub repository to understand the specific patches or enhancements included. While the difference in unpacked size isn't dramatically large, it indicates potentially relevant changes, especially for front-end developers dealing with bundle sizes or teams aiming to maintain maximum compatibility. The library ensures legacy browsers and environments can run modern Javascript, a major benefit for developers needing wider support.
