There is a const keyword in your javascript, but the webkit version in phantomjs doesn't yet support this syntax.

@Epskampie It works fine before...

Yeah, you used a new webpack, newer webpack targets modern browsers, modern browsers all support const, webpack outputs const, phantomjs doesn't support const. Q.E.D.

Downgrade your webpack, or don't use it at all.

@Epskampie That's too bad... seems I need to wait for PhantomJS support these features.

PhantomJS 2.5 will support full specification of ES2015.
