I certainly hope you are not using barewords like this. This will
work (for certain definitions of work) with the strict pragma turned
off, but it is a very bad idea. Please tell me the real code looks
like this
my @array = ('dadsad', 'assasd');
or
my @array = qw(dadsad assasd);

Besides needing indentation, this is okay. A better loop would name
the temporary variable (only use the default variable with functions
and operators that use it by default like chomp and regexes).
for my $item (@array) {
print "$item\n";
}

Well, yes, you can create a new array or scalar holding the
information, but it would just be a duplicate plus the newlines which
would be a waste of space. Why do you want this?
my @array_plus_newlines = map { "$_\n" } @array;
my $flattened_array_plus_newlines = join '', map { "$_\n" } @array;
