How to control string translation through camel to kebab filters and back again (this is a tip not a question)

Question

Putting this here in case anyone finds it useful.

Strings like 'ABC thing' when pushed through camel and kebab filters can cause unexpected issues. For example…

{% set str = 'ABC thing' %}
{% set key = str|camel %}
{% set id  = key|kebab %}
{% set keyFromId = id|camel %}

{# 
  key       = 'aBCThing'
  id        = 'a-bc-thing'
  keyFromId = 'aBcThing'
#}

Answer 1

The solution is to invoke lower first:

{% set str = 'ABC thing' %}
{% set key = str|lower|camel %}
{% set id  = key|kebab %}
{% set keyFromId = id|camel %}

{# 
  key       = 'abcThing'
  id        = 'abc-thing'
  keyFromId = 'abcThing'
#}
