Version Details and Security Vulnerabilities

Core-js is a widely used JavaScript standard library providing polyfills for modern ECMAScript features, ensuring compatibility across various browsers and environments. Versions 3.11.3 and 3.11.2, both under the MIT license and maintained actively with funding through Open Collective, offer reliable solutions for developers targeting broader browser support. Both versions maintain a consistent structure, residing in the packages/core-js directory within the main GitHub repository, ensuring easy access to the code and its history.

A crucial point for developers: while both versions have the same number of files (1775), version 3.11.3 exhibits a slightly larger unpacked size (720417 bytes) compared to 3.11.2 (719948 bytes). This suggests that version 3.11.3, released on May 5, 2021, contains some additional features, bug fixes, or performance enhancements, likely including updated polyfills or refinements to existing ones. In comparison, the previous version was released on May 3, 2021.

For those focused on having the most up-to-date and potentially optimized polyfills, upgrading to 3.11.3 is recommended. Developers should consult the changelog and release notes on the core-js GitHub repository for precise details on changes introduced in this specific version to understand any potential impact on their projects. Always consider testing your application after upgrading any dependency.
