Dependency deprecation warning: babel-preset-es2015 (npm)

On registry `https://registry.npmjs.org/`, the "latest" version (v6.24.1) of dependency `babel-preset-es2015` has the following deprecation notice:

`🙌 Thanks for using Babel: we recommend using babel-preset-env now: please read babeljs.io/env to update! `

Marking the latest version of an npm package as deprecated results in the entire package being considered deprecated, so contact the package author you think this is a mistake.

Affected package file(s): `package.json`

If you don't care about this, you can close this issue and not be warned about `babel-preset-es2015`'s deprecation again. If you would like to completely disable all future deprecation warnings then add the following to your config:

```
"suppressNotifications": ["deprecationWarningIssues"]
```

Start with package.json, where babel-preset-es2015 is listed, and review the deprecation notice's recommendation to use babel-preset-env. Done means the deprecated dependency is replaced and the project no longer reports this deprecation warning.
