| ``join``
========
The ``join`` filter returns a string which is the concatenation of the items
of a sequence:
.. code-block:: jinja
    {{ [1, 2, 3]|join }}
    {# returns 123 #}
The separator between elements is an empty string per default, but you can
define it with the optional first parameter:
.. code-block:: jinja
    {{ [1, 2, 3]|join('|') }}
    {# outputs 1|2|3 #}
Arguments
