  I’m trying to append a 'x2' to the end of a variable name to call another variable.
  
  For example:
  
  imgSize might be set to predefined variables like imgColumn4, imgColumn6 or imgColumn8.
  In that case I would also have imgColumn4x2, imgColumn6x2 and imgColumn8x2.
  
  So to simplify the variables in a loop, I’d like to do something like:
  
  ```
  {% set imageUrl = image.getUrl(imgSize) %}
  {% set imageUrlx2 = image.getUrl(imgSize ~ 'x2') %}
  
  ```
  
  `imgSize ~ 'x2'` does not work.
  
  How can I join 'imgSize' and 'x2'?

  There may be other ways also, but one approach is to use an array with key value pairs, which can be assigned and accessed more dynamically.
  
  ```
  {{ sizeVars[imgSize ~ 'x2'] }}
  
  ```
  
  You also might want to check out twigs `attribute` method.
  
  ```
  {{ attribute(array, item) }}
  
  ```
  
  Where 'item' can be a concatenated string.
