| ``first``
=========
.. versionadded:: 1.12.2
    The first filter was added in Twig 1.12.2.
The ``first`` filter returns the first "element" of a sequence, a mapping, or
a string:
.. code-block:: jinja
    {{ [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.
