Core-js is a modular standard library for JavaScript, encompassing features for modern ECMAScript specifications, web standards, and even proposes some additions to the language. Versions 3.18.1 and 3.18.0 share common ground, both under the MIT license and maintained by the same open-source collective. They provide crucial functionalities for ensuring compatibility across different JavaScript environments, polyfilling missing features in older browsers or runtimes. Developers rely core-js to use the latest JavaScript features without worrying about breaking compatibility with older setups.
The key changes between core-js 3.18.1 and 3.18.0 are incremental, but worth noting. Version 3.18.1, released on September 26, 2021, arrived just a week after 3.18.0 (September 19, 2021), suggesting it's likely a patch addressing minor bug fixes or small enhancements. The file count in the distribution increased slightly from 1879 to 1880, with a minor increase in unpacked size from 782202 to 782986, indicating a few additional files or edits.
For developers, this means that upgrading from 3.18.0 to 3.18.1 should be a safe and relatively painless process. Given the nature of patch releases, it's recommended to update to the latest version for stability and to benefit from any recent improvements. If the jump is to be from older versions is recommended to check the full changelog of the package.
