Ship ES5-compatible bundles

[benelliott]

Describe the feature you'd like:

Hi, would you be open to shipping Babel-transpiled ES5 bundles of this library? We are trying to use it over at https://www.github.com/netbasal/spectator but have trouble with IE11 compatibility because of the use of arrow functions in the current UMD bundles.

Suggested implementation:

Configure Babel to support IE11.

Dang it. It looks like some of our dependencies are not compiling themselves. That's pretty annoying. We'll need to figure out how to configure babel to compile node_modules.

This change will need to happen in kcd-scripts. Would you be willing to look into what must be done (probably here) to make that happen?

[NetanelBasal]

Thanks for the quick response. I guess it means that in general, the library doesn't support IE11.

Do we know which one is the problematic package?

Remove the exclude?

It looks like these arrow functions are coming from pretty-format, which does ship its own build-es5 module. Maybe if that was specifically loaded instead you wouldn't have to worry about reconfiguring Babel to compile your dependencies?

Alrighty, this has been fixed! Big thanks to @fobbyal in kentcdodds/kcd-scripts#72
