`babel-env` is an npm package that streamlines setting up a Babel toolchain for Node 6+ projects. By installing it as a dev‑dependency it automatically pulls in a curated set of Babel presets/plugins and generates (or keeps up‑to‑date) a default `.babelrc` file, with an opt‑out comment for projects that need a custom config. It’s aimed at JavaScript developers who want a ready‑made, consistent Babel environment without manually managing individual Babel packages.
