In JS, the comparator passed to sort() can potentially mutate the array that's being sorted, or delete it entirely. JS engines cope somehow.
Note that per spec the behavior if the comparator mutates the array is undefined. Engines are allowed to go into infinite loops, crash, throw exceptions, whatever. And sometimes do all of the above.
since any problems you can possibly come up with are already present in the existing Array#sort function.
