Can't use JS safe navigation yet (PR #18)

@eviltrout The build fails using the .? operator because of uglifier. Shouldn’t we be able to use it though? Can I use... Support tables for HTML5, CSS3, etc.


@markvanlan I was about to comment on the previous PR. The browser support for ?. is quite good (though Safari 13.1+ is quite recent, so that would exclude some percent of iOS devices) but the issue lies with some parts of our tooling, mostly uglifier, I think.

Yes uglifier is holding us back a little here. We looked at quick solutions last year but there was nothing easy we could do.

I think it will have to wait for Ember CLI to replace our deployment JS.
