What is this command doing? (PowerShell $?)

Anyone have any idea what this IF command is doing?

Connect-SPConfigurationDatabase -DatabaseName "$configDB" -Passphrase $secPhrase -DatabaseServer "$dbServer" -DatabaseCredentials $dbcreds -ErrorAction SilentlyContinue
    If (-not $?)
    {
        Write-Host -ForegroundColor White " - No existing farm found.`n - Creating config database `"$configDB`"..." }

I'm speculating it's an alternative to :

 Try { Do-Something -ea Stop }
 Catch { Write-host $_ }

but it's just that, speculation. I've never seen anything like this before and it's not showing up just the once in a script I'm inheriting. It's throwing me right off!

Thanks

$? is an automatic variable for the error status of the last executed command. See Get-Help about_Automatic_Variables.

Contains the execution status of the last operation. It contains TRUE if the last operation succeeded and FALSE if it failed.
