Hi r/powershell,

I am confused and I need a sanity check about scopes. Why is the output of this script changed?

Function ChangeIt {

    $Object.State = "Changed"

}

$Object = [PsCustomObject] @{

    State  = "Original"

}

ChangeIt

$Object.State

I always thought this would only work if I pass the object into the function as a parameter like this:

Function ChangeIt {

    Param(

        [PsCustomObject]$InputObject

    )

    $InputObject.State = "Changed"

}

$Object = [PsCustomObject] @{

    State  = "Original"

}

ChangeIt -InputObject $Object

$Object.State

But apparently, scopes don't seem to exist for [PsCustomObjects], or objects in general? Why do I even bother to pass objects as parameters into my functions then, if I have write access to them anyway?
