Not compatible with ES5

[c4ndybar]

Could we transpile this down to es5 so it is compatible with older browsers? The code appears to be ES6/7 compliant currently.

The features used in this module should be supported by pretty much all browsers with a usage > 0.5%. Are you really facing difficulties with users that use very outdated browsers?

Unfortunately, I have to target IE11 (which according to this site still has ~3% market share). You can see here that IE11 has almost no support for es6+ features.

I'm using a manually transpiled version right now, but that's obviously not ideal. I'd appreciate if you could transpile the library if it's not too much trouble.

@c4ndybar I added support for IE11 by removing the arrow function and let. This should be enough to target IE11. Please let me know if you run into any issues. Thanks.
