Arrays

Arrays are lists of items that can be iterated over or passed to other tags. {[one;two;three]} would create an array with 3 elements.

You can assign them to variables

{=myarray;{[one;two;three]}}
{$myarray}
{$myarray.0} // one

And you can iterate over them with {for}

{=target;{[one;two;three]}}
[#for;{=item};{$target}]
    {$item}
[/for]

... which would print

one
two
three
