Are There Ternary Operators in Powershell

usecase

The concern is documenting the need to have a conditional assignment of value similar as in Javascript with ternary operators in the situation where I need to have automatically created a folder name based on the current month, but have a leading zero for the first 9 months.

1. usual if statement

$folder = If ($MM -lt 10) {"0$MM"} Else { "$MM"}

2. ternary

• implemented in posh 7!

$folder = ($MM -lt 10) ? "0$MM" : $MM

CODE

• here is the code for the context

## the concern is to create a markdown file situated into proper folder YYYY/mm-YYYY/YYYY-mm-dd.md with date of yesterday (my diary)
function new-kron {
    $oneDay = New-TimeSpan -Days 1
    $today = Get-Date
    $yyyy = $today.Year.toString()
    $MM = $today.Month.toString()
    $MM = ($MM -lt 10) ? "0$MM" : $MM # ternary operator
    $yesterday = ($today - $oneDay).ToString("yyyy-MM-dd")
    $kronFolder = "c:\Users\Admin\Documents\familia\kron\$yyyy\$MM-$yyyy\"
    $kronPost = "$kronFolder\$yesterday.md"
    
    if (Test-Path $kronPost) { 
        Invoke-Item $kronPost 
    }
    else {
        New-Item $kronPost
        Set-Content $kronPost -Value "### $yesterday"
        Invoke-Item $kronPost
    }
}
