chomp(@array); # What are you iterating for? :)
chomp(@array = <STDIN>);
In short, chomp when you need to get rid of newlines
at the end of strings. There is no harm doing it
multiple times (just wasteful), and sometimes it is
just the last array element that needs chomped.
Easily fixed with:
chomp($array[-1]);
But usually I chomp on the loop, like most people:
while (<>) {
chomp;
...
}
If your algorithm doesn't care about the newline, and
you are outputing it again then leaving the newline
in isn't much of a problem (until you get to the last
line - which may/may not have a final newline).
