Just to solidify Aikon Mogwai's comment, you can do this with bracket notation on the array itself like this:

```js
var data = { arr: ['a','b','c'] }
var templateStr = "{{ arr[1] }}"
var result = nunjucks.renderString(templateStr, data) // 'b'
```

I would like to access the second value of an array in Nunjucks. Is this possible? I've read through the [documentation][1] but I can't seem to work it out.

`{{ array | first }}` and `{{ array | last }}` work, but is it possible to do something like `{{ array | second }}` ?

Access nth value of Array in Nunjucks

You can use one of the [built in filters][1] like [`lower`][2] to transform the string or nunjucks allows you to execute a limited set of JavaScript inside of expressions so calling `toLowerCase()` will also work.


Any of the following 3 approaches will work:

1 `{% if 'app' == role.toLowerCase() %} 1 {% endif %}`  
2 `{% if 'app' == role | lower %} 2 {% endif %}`  
3 `{% set role_lower = 'App' | lower %} {% if 'app' == role_lower %} 3 {% endif %}`

I'm trying to do a case insensitive match inside of an `{% if %}` statement

The following two approaches do *not* work:

```js
{% set role = 'APP' %}

{% if 'app' == role %}  1 {% endif %}
{% if 'app' in role  %} 2 {% endif %}
```

Nunucks only has a little documentation on their [comparison operators][1], but don't refer to specific types.

Nunjucks is a port of Jinja2 and there is a similar question on [how to lowercase a string in Jinja2][2]
