What was the problem with es6/Babel Promise?

[danielbreves]

It was 10 times the size and bigger than the SDK itself :/

[svizzari]

But it worked? Meh, Promise has pretty wide support, except for IE, it's a shame we can't use it and rely on browser availability 😿 Babel can transpile and optionally exclude certain features (if they're already available in target browsers), right?

[danielbreves]

Yea, it worked :)

@danielbreves This looks cool! I stopped commenting on a few instances of var that could be let, but otherwise, 👍

@sandlerr @ocke Give this some love if you get a spare minute, es6-ify everything!

[sandlerr]

is it possible to add a test case that the compiled artifact doesn't contain stuff that browsers don't support?

Testing whether babel works? All of our target browser versions have ES5 support, right?

[ocke]

ie9 and higher is es5, so yes.

[sandlerr]

Testing that we've configured babel correctly. I know people who have accidentally deployed ES6 to the web because the pipeline wasn't babelify a particular file, with bad results for IE9 users.

Closing in favour of #75
