If I have a hash
my %h = (
secret => 1;
);
and I know that is only is one key in the hash, but I don't know what it is called.
Do I then have to iterate through that hash
my $key;
foreach my $i (keys %h) {
$key = $h{$i};
}
Or are there a better way to get the name of the key?
A list slice should do it
(keys %h)[0]
keys
returns a list, so just extract the first element of that list.
