Description

Generally variables that are not used more than their assignments are considered wasteful and not needed.

How

Remove the variables that are declared but not used.

Example of incorrect code:

function Test
{
    $declaredVar = "Declared and used"
    $declaredVar2 = "Not used"
    Write-Output $declaredVar
}

Example of correct code:

function Test
{
    $declaredVar = "Declared and used"
    Write-Output $declaredVar
}
