Null coalescing in powershell

Question

Is there a null coalescing operator in powershell?

I\'d like to be able to do these c# commands in powershell:

var s = myval ?? \"new value\";
var x         


        

Answer 1

Finally, PowerShell 7 got Null Coalescing assignment operators!

PS > $null ?? "a"
a
PS > "x" ?? "y"
x
PS > $x = $null
PS > $x ??= "abc"
PS > $x
abc
PS > $x ??= "xyz"
PS > $x
abc
