An in-range update of core-js is breaking the build 🚨

[greenkeeper]

The dependency core-js was updated from 3.3.6 to 3.4.0.

🚨 View failing branch.

This version is covered by your current version range and after updating it in your project the build failed.

core-js is a direct dependency of this project, and it is very likely causing it to break. If other packages depend on yours, this update is probably also breaking those in turn.
