Hashes (Associative Arrays)

Note! This site is about Perl 6.
If you are looking for a solution for the current production version of Perl 5, please check out the Perl 5 tutorial.

A hash (also called associative array) is a set of key,value pairs where the keys are unique strings and the values can have any, err value.

Hashes always start with a % (percentage) sign.

tutorial/hash/create_hash.p6

#!/usr/bin/env perl6
use v6;

my %user_a = "fname", "Foo", "lname", "Bar";

my %user_b = 
    "fname" => "Foo", 
    "lname" => "Bar",
;

say %user_a{"fname"};
%user_a{"email"} = "foo@bar.com";
say %user_a{"email"};

say %user_b<lname>;

Output tutorial/hash/create_hash.p6.out

Foo
foo@bar.com
Bar
