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 by inspecting the dependency entry in package.json and consult the Babel migration guidance linked in the deprecation notice. Replace the deprecated preset as appropriate, then verify that the dependency warning is no longer reported.
