💥  preset-latest accomplishes the same task as babel-preset-env. 🙏  Please install it with 'npm install babel-preset-env --save-dev'. '{ "presets": ["latest"] }' to '{ "presets": ["env"] }'. For more info, please check the docs: http://babeljs.io/docs/plugins/preset-env 👌. And let us know how you're liking Babel at @babeljs on 🐦

Attempted this - there seems to be some incompatibility with the latest stuff, so I'm going to leave it as is for now with a help wanted tag.
