This works, but there can be some improvements.
Check that elements is an array before calling .filter(), and do an early return if it is empty.
Sorting the entire array is unnecessary if you only need the maximum value.
Consider using Number.isFinite() to ensure only valid numbers are included, so no need for typeof element === "number"

You could book a pair programming session.
Before then, try to read this:

You just need to replace that check, but you need to know why you are doing it.
