Core-js version 3.15.1 is a minor update to the popular JavaScript standard library, building upon version 3.15.0. Both versions are MIT-licensed and readily available on npm, serving as comprehensive collections of polyfills and shims, enabling developers to use the latest ECMAScript features in older environments. This ensures that modern JavaScript code can run seamlessly across a wide range of browsers and Node.js versions, boosting compatibility and reducing the need for complex conditional logic based on runtime environments. Both are backed by the same open collective funding too.
Key differences arise in the details: While both packages contain the same number of files (1817), version 3.15.1 sees a very slight reduction in the unpacked size, hinting at possible optimizations. The unpacked size is 741555 for the newer version, compared to 741650 of the older one. More importantly, version 3.15.1 was released on June 22, 2021, two days after version 3.15.0. This short interval suggests that the newer release likely addresses bug fixes, performance improvements, or minor feature refinements discovered soon after the initial 3.15.0 release. Developers should therefore consider upgrading to 3.15.1 for the most stable and up-to-date experience, leveraging the continuous improvements and refinements offered by the core-js team.
