Babel-runtime versions 5.8.20 and 5.8.19 offer essential runtime support for Babel-compiled code, ensuring compatibility across different JavaScript environments. Both versions, licensed under MIT, provide a "selfContained runtime," meaning they include necessary polyfills and helper functions within a project, preventing conflicts with other libraries or global scope pollution. Key dependencies for both versions include babel-plugin-runtime and regenerator, crucial for enabling features like async/await via regenerator functions. They also share the same author, Sebastian McKenzie, and the same repository on GitHub.
The primary difference lies in their core-js dependency. Version 5.8.20 upgrades to core-js version ^1.0.0 from ^0.9.0 in version 5.8.19. This update likely incorporates new polyfills, performance improvements, or bug fixes present in core-js v1.x. Developers choosing between these versions should consider the specific features and fixes introduced in core-js 1.0.0. For projects requiring the latest ECMAScript features and improvements, version 5.8.20 ensures access to those advancements through the updated core-js dependency. Version 5.8.20 was released on July 31, 2015, while version 5.8.19 was released on July 29, 2015. Therefore, upgrading to version 5.8.20 will provide you with the latest stable version.
