Could you get the filename by doing something like:
const filenameWithExtension = u.pathname.split('/').pop();
Similar to line 204 but gets the last immedately.

Then extension:
const fileExtension = filenameWithExtension.split('.').pop();

I see the loop goes backwards (handling periods in path segments), which works but might be a little awkward to read.
