How to check if an associative array is empty in powershell

powershell hashtable powershell-4.0 is-empty

That's not an associative array, it's a regular array, but the answer is the same. Use .Count and compare to 0.

An associative array is called a [hashtable] in PowerShell and its literal form uses @{} (curly braces).

@{}.Count -eq 0  # hashtable (associative array)@().Count -eq 0  # array

powershell hashtable powershell-4.0 is-empty

Arrays have Count property, and you can check if this value is 0. So the condition you would check for is

$a.Count -eq 0
