How to sort the date form to latest to the oldest in array of objects react js

im trying to sort the date from this array of objects from the latest to the oldest. Im trying this code, copying the array to a new const then using it with sort, but I have the same result, no sorted date. My code is below:

const array=[...user?.editedBy]
console.log(array,"array")

const sortedDates = array?.sort((dateA, dateB) => dateB.date -dateA.date )
console.log(sortedDates,'sortedArray')

The first pic its the console log from array and the second from sortedDates,
So the same result, can someone please help me figure it out what Im missing???
*Thank you in advance *
