"a.reverse( );" : Replace the array
"a.slice().reve rse();" : Display only without replace the arrayComment

more accurate would be:"a.reverse( );" : Replace the array
"a.slice().reve rse();" : Display only without replace the array
a.reverse(); - mutates the array a
a.slice().rever se(); - mutates a new array that was returned by the slice method - so the original array a would stay unmodifiedComment
