Quickly and dirty determine if a condition is true or false in PowerShell 5.1 by emulating the ternary operator. For example when determinering if the server you are servicing is a Windows Server Desktop Experience version or not (and thus Server Core):
$condition = (Get-CimInstance Win32_OptionalFeature | Where-Object Name -eq 'Server-Gui-Mgmt').InstallState
({true}, {false})[!$condition]This returns true for a GUI enabled Windows Server instance and false for Windows Server Core.

And yes, PowerShell Core 7 (pwsh) supports it natively:
(Get-CimInstance Win32_OptionalFeature | Where-Object Name -eq 'Server-Gui-Mgmt').InstallState ? "true" : "false"
false
