Package 'module' field is in ES6 syntax -- incompatible with IE

[josephliccini]

Hi,

I am trying to consume this package with webpack, which will use the module field in package.json.

That module field points to a ES6 version of the package. I believe module should be used for ES6 import / export syntax, but still needs to be runtime compatible with ES5.

This leads to webpack pulling in an ES6 class which causes a syntax error in IE.

This is intentional. See an equivalent discussion here.
