Browser Support

• evergreen / IE9+ / Safari 6.1+ https://github.com/github/fetch#browser-support

does this replace ic-ajax?

• ideally yes, but only if you cater to IE9+
• for basic drop-in compat import ajax from 'fetch/ajax'

What about all the run-loop and promise mixing details?

• taken care of for you

why is this wrapper needed?

• original emits a global
• original requires a Promise polyfil (ember users have RSVP)
• original isn't Ember run-loop aware

Won't this wrapper get out-of-sync?

• we actually don't bundle github/fetch rather we merely wrap/transform what comes from node_modules, so we should be resilient to changes assuming semver from the fetch module
