``iterable``
============

.. versionadded:: 1.7
    The iterable test was added in Twig 1.7.

``iterable`` checks if a variable is an array or a traversable object:

.. code-block:: jinja

    {# 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 %}
