AFAIK your version, which looks good, is missing the following line below the normalize one:
replace( /[\u0300-\u036f]/g, '' )
The normalize()
function splits each accented character in two: the base character, and its accent.
The subsequent replace()
line deletes all the accents, which happen to be all in the \u03xx UNICODE block.
Removing the accents requires these two steps.
I got the info for my slugify version from June 6, 2020 from the MDN docs:

Works! thanks.

Added that in, and also a line to change underscores to hyphens. May not be perfect but its good for my uses!
