Core-js is a JavaScript standard library offering polyfills for ECMAScript features, enabling developers to use modern JavaScript syntax and functionality across various environments, even older browsers. Comparing versions 0.9.1 and 0.9.0 reveals a subtle but essential update: a bump in the eslint dependency, moving from version 0.19.x to 0.20.x. While seemingly minor, this signifies an improvement in code linting and style consistency within the core-js development process, indirectly benefiting developers by ensuring a more robust and reliable library.
Both versions share the same core functionality, providing comprehensive polyfills and shims for standard JavaScript features. Developers can leverage core-js to write future-proof code, knowing that necessary functionalities will be provided even in legacy browsers. Shared development dependencies like Grunt, Karma, and Webpack facilitate testing and bundling, ensuring cross-browser compatibility and efficient integration with modern JavaScript workflows. The promises-aplus-tests dependency indicates a strong commitment to Promises/A+ spec compliance, making it a solid choice for asynchronous programming. The MIT license promotes broad use and modification, inviting community contributions and widespread adoption. These versions maintain a focus on polyfilling fundamental JavaScript features, allowing developers to confidently adopt newer ECMAScript syntax.
