Generally other DSLs are other applications you will need with bash to accomplish your goal like grep, curl, jq and others. For example, to hit a rest API, parse the response and then do something based on the response in bash would require curl, jq to properly handle it. Powershell wouldn't require that since Invoke-RestMethod would return dictionary that easily handled. Also, for applications that can return JSON like kubectl, it can easily turn those into objects with ConvertFrom-JSON

Think of Powershell as replacement for bash AND python with built in CLI library. You can run interactively to do little stuff but if you need heavier lifts that requires a script with prompts and all that, you got it.
