a new untouched glimmerjs app with ember new my-app -b @glimmer/blueprint ran in firefox and chrome but not in ie or edge.
Edge gave me following error:
SCRIPT1028: Expected identifier, string or number:
app.js (3386,11)
IE11:
SCRIPT1002: Syntaxfehler
app.js (7,1)
After adding IE11 in config/targets.js the app runs with "Microsoft Edge", but still not with IE11.
IE11 provides following error, which referes to a let Symbol:
SCRIPT5009: "Symbol" ist undefiniert
app.js (9804,1)
Any other settings we need to change?
Also it's a little bit strange that with setting IE11 the Edge problem got fixed.
Or that the default setting 'last 2 Edge versions' does not transpile to a edge compatible version...
We got a little bit further with IE 11 and Edge support in https://github.com/glimmerjs/glimmer.js/issues/8
But still were not able to completely solve it in order to support IE 9 and 10 also.
