JS inbuilt sort function step by step observing sort

in webinar 08 at 1:30:10 output is not coming as expected

let arr=[6,3,9,1,7,2,14,26,35]
function compare(a,b){
return b-a;
}
arr.sort( function(a,b) {
console.log(arr)
console.log(a+" "+b)
return a-b;
} )
console.log(arr)

chrome console o/p
[ 6, 3, 9, 1, 7, 2, 14, 26, 35 ]

[ 6, 3, 9, 1, 7, 2, 14, 26, 35 ]
14 26
[ 6, 3, 9, 1, 7, 2, 14, 26, 35 ]
26 35
[ 1, 2, 3, 6, 7, 9, 14, 26, 35 ]
final answer is sorted but i can’t see step by step sorting process
also console.log(a+" "+b) <— in chrome console 6 3 gets printed but in vs code 3 6. why so
console.log(arr)
[ 6, 3, 9, 1, 7, 2, 14, 26, 35 ]
6 3
