Core-js is a JavaScript standard library offering polyfills for modern ECMAScript features, ensuring compatibility across various JavaScript environments. Examining versions 2.1.3 and 2.1.2 reveals a narrow time gap between releases, both occurring on February 29, 2016. This suggests a quick succession of updates, likely addressing bug fixes or minor improvements. For developers, this close proximity implies a low-risk upgrade path. Given the identical "devDependencies" field, both versions relied on the same suite of development tools (including webpack, grunt, karma, and eslint). This consistency is reassuring, as it means no significant changes were made to the build process or testing infrastructure.
The similarity of the dependency list also suggests the core functionality and intended environment for each version remained the same. Both versions are licensed under the MIT license which is a permissive open-source license. The package is stored in the same repository. Because the only difference between the two versions is the minor version update, upgrading to 2.1.3 from 2.1.2 would likely be safe and a valuable update including bug fixes. For those looking to incorporate modern JavaScript features in their projects while supporting older browsers or environments, core-js, whether version 2.1.2 or 2.1.3, provides a valuable solution. While this description focuses on these specific versions, it's crucial to always consult the official changelog for the most accurate and detailed information before upgrading.
