An Hash is a dynamic collection of key-value pairs. The keys must be of type String, while the values can have any type.

    a => 1,
    b => 2,
    c => 3,

Working with hashes:

Elements of an hash can be accessed with the special syntax hash{key} where key is a String-convertable object.

var hash = Hash(name => 'Sidef')

# Print the value of a key
say hash{"name"}      #=> "Sidef"

# Set a key into the hash
hash{"age"} = 6

# Print the hash
say hash

Existent key

A key can be checked if it exists in a hash using the syntax: hash.exists(key).

Deleting a key

A key can be deleted from a hash using the syntax: hash.delete(key).
