``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.
