Key elements like the author, Denis Pushkarev, and funding through Open Collective remain consistent.

This suggests minor additions or adjustments within the codebase. The file count remains identical at 3338.

For developers, core-js offers a robust solution for polyfilling new JavaScript features, enabling them to use cutting-edge syntax and functionalities without worrying about browser compatibility. The library is designed to be modular and tree-shakeable, minimizing bundle sizes by including only the necessary polyfills. While the difference between versions 3.30.1 and 3.30.2 seems minimal, it's always recommended to check the official changelog or release notes for specific details on bug fixes, performance improvements, or new features included in the latest version.
