es6-promise: Possibly unhandled error should be thrown

Node v0.10, non-harmony. Such as:

var Promise = require('bluebird');
new Promise(function () { throw('err') });
// Unhandled error will be thrown.

var Promise = require('es6-promise').Promise;
new Promise(function () { throw('err') });
// Nothing will happen.

Stop using the polyfill when you are assign the es6-promise after that anyway es6-promise.polyfill() is broken for Chrome atm and replaces the native Promise and swallows unhandled errors. https://gi... — committed to jitsi/lib-jitsi-meet by deleted user 8 years ago

The means to catch unhandled rejections is a part of ECMAScript 2017 Draft spec (as HostPromiseRejectionTracker). Looking forward to see it in this library!

Ya, still trying to find time 😉 It will land, I was a big proponent of the feature in the first place.

Chrome currently logs unhandled errors. Firefox does it on GC.

Happy to do the same as Chrome here. It should be a log rather than a throw, we’d be spec-breaking if it appeared in window.onerror.
