Answer 1

also for both asec and desc sort, u can use this : suppose we have a variable SortType that specify ascending sort or descending sort you want:

 users.sort(function(a,b){
            return   sortType==="asc"? a.firstName.localeCompare( b.firstName): -( a.firstName.localeCompare(  b.firstName));
        })
