krsort
The krsort filter sorts an array or hash in reverse order by its keys.
You would typically save the sorted array back to the original variable or to a new variable.
{% set array = array|krsort %}
{% set hash = hash|krsort %}
You can use this filter within a for loop.
{% for item in items|krsort %}
...
{% endfor %}
You can also use this filter in combination with the join filter to sort and output the array values in one step.
{{ [5,8,2,3]|krsort|join(', ') }}
That would output: 8, 5, 3, 2
