You can use the array methods find and lastIndexOf/indexOf to do this in a more direct manner:
find
lastIndexOf
indexOf
return array.find((item) => array.indexOf(item) === array.lastIndexOf(item))
find has the added advantage over filter that it stops iterating after the first match. Sorting the array will only work for numbers, strings or objects that can be coerced to either.

Great solution for optimizing the code, thanks bro! 🙌🔥
