perl hash ref create

To create a Perl hash reference, you can use the curly braces {} to define an anonymous hash and assign it to a scalar variable. Here's an example:

my $hash_ref = {
    key1 => 'value1',
    key2 => 'value2',
    key3 => 'value3'

In this example, $hash_ref is a scalar variable that holds a reference to the anonymous hash. You can access the values of the hash using the arrow operator ->. For example, to access the value associated with key1, you can use $hash_ref->{key1}.

Please note that the code provided is a basic example, and you can add more key-value pairs to the hash as needed.
