Description:

Use reverse in scalar context. It just reverses by bytes or characters. In a list context it will reverse the elements of a list:
$revstr = reverse($str); # reversed by character $revwords = join(" ", reverse split(/ /, $str));

This also works for reversing the order of words, but is trickier.

$str = 'hacker. Perl another Just';
($revwords = $str) =~ s/(\S+)/reverse $1/ge;
$revwords = reverse $revwords
