| ``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. | |
