Version Details and Security Vulnerabilities

Core-js version 2.5.5 represents a minor update following the 2.5.4 release, both iterations serving as standard Javascript libraries that provide polyfills for modern ECMAScript features, ensuring compatibility across various environments. A subtle difference lies in the realm of development dependencies. Version 2.5.5 upgraded eslint-plugin-import from 2.9.x to 2.10.x, a change that typically brings improvements in ES module import linting, potentially offering enhanced code quality and fewer errors during development.

While the core functionality remains largely consistent between the two releases, developers leveraging eslint during their build process might find the updated linting rules valuable. The fileCount remains the same at 1473, indicating that there were no major additions or removals of files. The unpacked size has a sligh variation increase in version 2.5.5, indicating the size of the packaged library is bigger than the previous one. Both versions share identical tooling and testing frameworks, including webpack, karma, and grunt, underlining a consistent development and testing approach. If you're using core-js in a project, upgrading to 2.5.5 likely poses minimal risk, and those relying on eslint-plugin-import may find benefit from the improved linting capabilities. Otherwise, the core functionality and polyfills remain consistent and reliable in both versions.
