{% set key = 'something' %}

My array has key something, I and can it access array['something'], but when I try to use variable in key like:

array[key]

You can use the attribute function:

{{ attribute(array, key) }}

From the doc:

addition, the defined test can check for the existence of a dynamic attribute:
{{ attribute(object, method) is defined ? 'Method exists' : 'Method does not exist' }}

Hope this help
