+## Babel Transform Runtime plugin options
+
+By default, Babel Transform Runtime plugin is configured to **not** transform new built-ins (Promise, Set, Map, etc.) to use a non-global polluting polyfill ([Babel Runtime transform plugin documentation](https://babeljs.io/docs/plugins/transform-runtime/)).
