map

The map filter applies an arrow function to the elements of a sequence or a mapping. The arrow function receives the value of the sequence or mapping:

1
2
3
4
5
6
7
{% set people = [
    {first: "Bob", last: "Smith"},
    {first: "Alice", last: "Dupond"},
] %}

{{ people|map(p => "#{p.first} #{p.last}")|join(', ') }}
{# outputs Bob Smith, Alice Dupond #}

The arrow function also receives the key as a second argument:

1
2
3
4
5
6
7
{% set people = {
    "Bob": "Smith",
    "Alice": "Dupond",
} %}

{{ people|map((value, key) => "#{key} #{value}")|join(', ') }}
{# outputs Bob Smith, Alice Dupond #}

Note that the arrow function has access to the current context.
