Promise Dependency - TypeError: Promise.all is not a function

[bartolomeu]

When I use pptx.save() throws

TypeError: Promise.all is not a function

That's caused by this call in the dist/pptxgen.js:1522
Promise.all( arrChartPromises )

in the file bower.json:10 there is the dependency of promise:
"promise": "^0.2.2"

PromiseJS doesn't have implemented all()

The main question is Promise is implemented by ECMAScript 2015 (6th Edition, ECMA-262) according with MSN

Chrome - 32.0
Edge - (Yes)
Firefox - 29.0
Internet Explorer - No
Opera - 19
Safari - 7.1

Just removing the dependency of promise will make the the browser use the native Promise from ECMA and finish this problem, that I belive only occours installing through bower.

Hi @bartolomeu ,

Thanks for letting me know about this. As you pointed out the only reason to have the polyfill is for IE11, everyone else has it.

Therefore, i've just removed that dependency altogether. We'll be dropping IE11 support soon anyway, so hopefully there are not many users impacted.
