Question

How do I count the elements of an array stored in a hash? When I want to alter the elements I would do it like this:

$myObject->{document}->[$i]->{myValue};

Somehow I don’t get how to get document’s count.

I’m new to Perl and all the approaches I’ve tried work fine for regular arrays, but not for those stored in a hash.

Simply dereference the arrayref:

my $count = @{ $myObject->{document} };
