Unix time based sorted array is not sorting correctly

Question

I've UNIX timestamps in a response and I'm sorting them as:

var sortedData = data.sort(function (x, y) {
    return x.created - y.created
})

Here are some of the values of created

1612840160306
1612717863299
1612715819573
1612853308834
1612842118101
1612767742861
...

Then I'm passing the sortedData to a state which then re-renders as:

                        {userSortedData.map((data, index) =>
                            <MyTestCell
                                key={index}
                                name={data.personName}
                                phone={data.phone}
                                createdOn={data.created}
                            />
                        )}

In my view, I can see that the first cell is assumed

And a cell below it is

Whereas it should be that the cell displaying Feb 7 date should be above Feb 6 but it's not.

whatever you did is working perfectly fine, but in ascending order thus you are seeing in 6th before 7th. Try descending order data.sort((x, y) => y.created - x.created). — Ravikumar
