I am trying to figure out the syntax to be able to reference a variable within an each loop and replace it with the loop variable.

Here is a very simple example of what I am trying to do.

trigger:
  branches:
    include:
      - develop

variables:
  - name: regions
    value: ncus,scus
  - name: webAppName
    value: myapp-<region>

stages:
- stage:
  jobs:
  - ${{ each region in split(variables.regions, ',') }}:
    - job:
      pool:
        vmImage: 'windows-latest'
      steps:
      - script: 'echo "replace(webAppName, <region>, region)"'

What I want is the output of the echo statement in the script task to be myapp-ncus and myapp-scus. I know the syntax I have here is incorrect, I just wanted to give some pseudocode representation of what I am trying to do. I’ve tried all combinations of $(), ${{ }}, $[], but nothing seems to work.
