published pre-compiled ES5

ES5 is required for making a build of react app

I'm not sure for certain, but I think this package is intended for nodeJS environments, not the browser.

I'd consider trying the other options suggested by that link:

• Fork the package and publish a corrected version yourself.
• If the dependency is small enough, copy it to your src/ folder and treat it as application code.

This is a very small dependency, so shouldn't be too difficult to attempt either of those.

If you figure out how to correct the issue, perhaps you could open a PR here!
