@alexcarol not sure if its the best place to add it, but I have alternate langauges links being added to the head, which enables the language switcher. (The icon is misaligned for some reason, but that is for another task.)

I can't get past some of the linter errors. One makes no sense: it says splitPattern isn't used, but it clearly is 4 lines later. I tried modifying some of the other issues but it just ends up breaking my code.

I don't see "splitPattern" used anywhere, are you looking for it in the diff or in your editor? (in case there's changes that might not be pushed). Can you share a link to the line where it's used?

Well that's really weird. You and the linter couldn't see it. Literally there on line 60 and 64. Whatever; moving on.

Oh! The error changed. I see it is failing AFTER line 64 now. I was getting errors that it was never declared. Anyway... moving on.

The issue was that it was assigned, but never read, so it's essentially not "used".
