Hey Guys,
I think the Service Studio should be support jsHint - ES6, this integration will provide more results on Mobile development.
Also on Javascript screen show thats as warning, but when you close it, shows an error on service studio, I think need be improve the syntax of this Warning on screen and Error on Service Studio.
If is not supported, show an error, not a warning.
Info: Service Studio version: 10.0.807 and platform server version 10.0.710
