Perl Array reverse() Function - Quick Tutorial

 @REVERSED_LIST = reverse(@ARRAY); 

Perl's reverse() function is used to reverse the order of an array. It should be noted that the function returns a reversed array but does not actually reverse the array passed into the function.

 @myNames = ('Jacob', 'Michael', 'Ethan', 'Andrew');
@reversedNames = reverse(@myNames); 

Think of the @myNames array as a row of numbered boxes, going from left to right, numbered starting with a zero. The reverse() function would copy the contents of the boxes from the @myNames array into the @reversedNames array, while reversing their order. The value of @reversedNames then becomes ('Andrew', 'Ethan', 'Michael', 'Jacob'), and @myNames remains the same.
