Promise version

[olup]

Can I suggest a promisified version of this ? I had to encapsulate it - but getting it out of the box in case no callback is provided would be a must !

Hi @olup, I definitely understand the pain of having no promise by default, but this was done for a reason.

IE 11 doesn't support promise :(

In order to keep the size small, I left it to the users to decide what Promise wrapper/polyfill they choose to use instead of bundle one with this package. I hope this makes sense :)

Oh, I see, didn't get this ie11 requirement. I'll close this then.
