linklists[block.settings.linklist] what happends there?

[thalpie]

Ive just started developing in liquid and ive seen this iteration through a link list

{% assign linklist = linklists[block.settings.linklist] %}
{% for i in (0..linklist.links.size) %}
<li><a href="{{ linklist.links[i].url }}" >{{ linklist.links[i].title }}</a></li>
{% endfor %}

{% endif %}

my question here is what does linklists[] do to the block.settings.linklist object ?

[Slava_Maksimov]

linklists takes the navigation menu handle and returns the linklist object
