Core-js is a JavaScript standard library providing polyfills for ECMAScript features, allowing developers to use modern JavaScript functionality in older environments. Version 0.4.4, released on January 11, 2015, builds upon the preceding stable version 0.4.3, released just a day before on January 10, 2015. While both versions share identical descriptions, development dependencies like grunt, karma, LiveScript, and testing tools, the release date indicates a quick follow-up release, suggesting a minor bug fix or improvement. Developers leveraging core-js gain access to cutting-edge JavaScript features without sacrificing compatibility with browsers and JavaScript engines lacking native support. The library ensures consistent behavior across platforms by providing implementations for features like promises, symbols, collections, and iterators, as well as other essential functionalities. Choosing between 0.4.3 and 0.4.4 likely depends on whether the specific fix or improvement introduced in 0.4.4 addresses a known issue encountered by the developer, as no specific changelog is provided in the metadata. The library's repository on GitHub provides further details and documentation, enabling developers to explore the available features and contribute to the project. Consider that this is a very old version, so there could be breaking API changes respect to newer versions.
