Doubt about internal working of sort function

#1

As you told that internally it is using if(comparatorfunction) for swapping so
consider array 1 2 3 i want to reverse this array so as you have used return a>b
1>2 return false no swapping
2>3 return false no swapping
so the array should remain same ?
but it is reversed in output so how does it actually working ?

#2

Actually when you compare 1 and 2
1>2 ? False. So we swap.
2>1 > True. So keep as is.
