Does Perl have reference type?
Does Perl have reference type
✍: Guest
Yes. Perl can make a scalar or hash type reference by using backslash operator. For example:
$str = "here we go"; # a scalar variable $strref = \$str; # a reference to a scalar @array = (1..10); # an array $arrayref = \@array; # a reference to an array
Note that the reference itself is a scalar.
