Where-Object not filtering - powershell

Question

Why isn't where-object working in this case?
$controlFlowArgs = #{ waitForEnter = $false }
$controlFlowArgs | Format-Table
$controlFlowArgs | Format-List
$result = $controlFlowArgs | Where-Object -FilterScript { $_.Name -eq "waitForEnter" }
$result
Output
Name Value # Format-Table
---- -----
waitForEnter False
Name : waitForEnter # Format-List
Value : False
# Missing result would be here

Answer 1

$controlFlowArgs is a HashTable. You should probably think it differently.
$result = $controlFlowArgs | Where-Object { $_["waitForEnter"] }
would store $false in $result.
Else you can use the Hashtable directly:
if ($controlFlowArgs["waitForEnter"]) {
...
}

Answer 2

Where-object is working fine. In this example, only the 'joe' hashtable appears. Confusingly the format takes up two lines.
#{name='joe';address='here'},#{name='john';address='there'} | ? name -eq joe
Name Value
---- -----
name joe
address here
It's still considered one thing:
#{name='joe';address='here'},#{name='john';address='there'} | ? name -eq joe |
measure-object | % count

If you want the value itself, use foreach-object (or select-object -expandproperty):
#{name='joe';address='here'},#{name='john';address='there'} | ? name -eq joe |
% name
joe
Usually powershell works with pscustomobjects:
[pscustomobject]#{name='joe';address='here'},
[pscustomobject]#{name='john';address='there'} | ? name -eq joe
name address
---- -------
joe here
