Perl language variable types

in perl, there are three data types
1)scalar
  my $animal ="camel";
  my $amswer = 42;
2) arrays
  my @animals =("camel","llama","owl");
  my @numbers = (23,42,69);
  my @mixed = ("camel",42,123.56);
3)hashes
   my %fruit_color = ("apple","red","banana","yellow");
   my %fruit_color =(apple=>"red",banana =>"yellow",);
