| ``iterable`` | |
| ============ | |
| ``iterable`` checks if a variable is an array or a traversable object: | |
| .. code-block:: twig | |
| {# evaluates to true if the foo variable is iterable #} | |
| {% if users is iterable %} | |
| {% for user in users %} | |
| Hello {{ user }}! | |
| {% endfor %} | |
| {% else %} | |
| {# users is probably a string #} | |
| Hello {{ users }}! | |
| {% endif %} |
