Version Details and Security Vulnerabilities

Babel-runtime versions 5.1.10 and 5.1.9 are closely related releases of the self-contained runtime library for Babel, the popular JavaScript transpiler. Both versions share the same core functionality, providing essential polyfills and helper functions needed to execute Babel-transformed code in environments that may lack native support for newer JavaScript features. They are authored by Sebastian McKenzie and rely on the core-js library (version ^0.8.0) to provide many of the necessary polyfills. The repository location remains constant at the babel/babel GitHub repository.

The primary difference between the two versions lies in their release date. Version 5.1.10 was published on April 15, 2015, while version 5.1.9 was released a day earlier, on April 14, 2015. This suggests that version 5.1.10 likely contains bug fixes or minor improvements implemented shortly after the 5.1.9 release.

For developers considering using Babel-runtime, the library offers a convenient way to avoid polluting the global scope with polyfills. Instead, the necessary helpers are included directly within the compiled codebundle that will consume babel-runtime. If you want to enhance compatibility with older browsers or environments without full ES6+ support, installing babel-runtime will help you make the code from newer versions of ECMAScript run in any environment. Because the difference in versions is small, it's advisable to utilize the latest stable release (5.1.10 in this case or a more recent one).
