Perl sorting hash by values in the hash

Question

I think I have the right idea but there\'s some syntax/convention thing I\'m messing up, because I get the error \"Global symbol %timeHash requires explicit package name\".

Answer 1

use List::UtilsBy qw( rev_nsort_by );

foreach my $key ( rev_nsort_by { $timeHash{$_} } keys %timeHash ) {
    ...
}
