How to set PowerShell variables to True or False

PowerShell logic question:

$a = 1
$b = 2
if ($a = $b) {
    $ans = $true
}
else {
    $ans = $false
}
Write-Host $ans


Output:
True

Can someone explain to me why this evaluates as true? Is it because I assign $ans to true first? Also, could someone show me how to get this to evaluate the way I think it should?

You're doing an assignment $a = $b, the assignment succeeds and that returns true because b was true, so the first case will always evaluate to true at the moment, instead use a comparison: $a -eq $b.

More detailed information on comparisons in powershell.
