=abstract start

I guess there is not much to say about the <hl>join</hl> function except that
it is the counter part of the <hl>split</hl> function.

=abstract end

This function can take several elements of a list or an array and join them together into a string.

<code lang="perl">
use strict;
use warnings;
use v5.10;

my @names = ('Foo', 'Bar', 'Moo');
my $str = join ':', @names;
say $str;                       # Foo:Bar:Moo

my $data = join "-", $str, "names";
say $data;                      # Foo:Bar:Moo-names


$str = join '', @names, 'Baz';
say $str;                       # FooBarMooBaz
</code>

The first paramter of the <b>join</b> function is the "connector",
the string that will be connecting all the other parameters.
The rest of the parameters of join will be flattened to a
list and the elements will be glued together with the given "connector".

This "connector" can be any string, even the empty string.
