``join`` ======== The ``join`` filter returns a string which is the concatenation of the items of a sequence: .. code-block:: twig {{ [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:: twig {{ [1, 2, 3]|join('|') }} {# outputs 1|2|3 #} A second parameter can also be provided that will be the separator used between the last two items of the sequence: .. code-block:: twig {{ [1, 2, 3]|join(', ', ' and ') }} {# outputs 1, 2 and 3 #} Arguments --------- * ``glue``: The separator * ``and``: The separator for the last pair of input items
