Should core-js be in dev dependencies?

[xPaw]

It's needed for the browser build as it's used by babel, does it need to be in production dependencies?

Same question for regenerator-runtime, as I don't see it being used directly.

cc @vith for insight, as you added both of these.

They're both used at runtime. Their usage is injected by babel, you can only see it when looking at the build output. They provide various polyfills to enable older browser support.

Makes sense, thanks.
