fix eslint warnings

Thanks for working on those. It's still throwing errors, so I guess this needs work.

eslint passed.

Nice job! Two problems though: the summary information is now broken. If you go to /admin/structure/ds/settings and select something in the 'Other' or 'BC settings' tab, the values aren't printed. Will have a look if I can help out there, it's really close!

Working now.

Awesome, thank you!
