reverse

The reverse filter reverses a sequence, a mapping, or a string:

{% for user in users | reverse %}
  ...
{% endfor %}

{{ '1234' | reverse }}
{# outputs 4321 #}

For sequences and mappings, numeric keys are not preserved. To reverse them as well, pass true as an argument to the reverse filter:

{% for key, value in {1: "a", 2: "b", 3: "c"} | reverse %}
  {{ key }}: {{ value }}
{%- endfor %}

{# output: 0: c 1: b 2: a #}

{% for key, value in {1: "a", 2: "b", 3: "c"} | reverse(true) %}
  {{ key }}: {{ value }}
{%- endfor %}

{# output: 3: c 2: b 1: a #}
