Counting the number of elements in array

Question

I am looking to count the number of entries I have in an array in Twig. This is the code I\'ve tried:

{%for nc in notcount%}
{{ nc|length }}
{%endfor%}
         


        

Answer 1

This expands on the answer by Denis Bubnov.

I used this to find child values of array elements—namely if there was a anchor field in paragraphs on a Drupal 8 site to build a table of contents.

{% set count = 0 %}
{% for anchor in items %}
    {% if anchor.content['#paragraph'].field_anchor_link.0.value %}
        {% set count = count + 1 %}
    {% endif %}
{% endfor %}

{% if count > 0 %}
 ---  build the toc here --
{% endif %}
