`first`

The first filter returns the first "element" of a sequence, a mapping, or a string:

.. code-block:: twig

{{ [1, 2, 3, 4]|first }}
{# outputs 1 #}

{{ {a: 1, b: 2, c: 3, d: 4}|first }}
{# outputs 1 #}

{{ '1234'|first }}
{# outputs 1 #}

.. note::

It also works with objects implementing the `Traversable`_ interface.
