Powershell foreach loop with additional variable and break

I am still new to powershell, right now I study foreach with break, I understand the concept, but when it combined with additional variable and break; it confuses me, here is the code:

$i=0
$varZ = (10,20,30,40)
foreach ($var in $varZ)
{
    $i++
    if ($var -eq 30)
    {
        break
    }
}
Write-Host "30 was found in array position $i"

the result I get showing that variable $i = 3, where $var = 30 but what confuses me, as I understand $i starts with 0 and there is an array $varZ (10,20,30,40), as I understand when $i = 0 $var = 10, hence $i = 3 $var = 40? please correct me and help me understand this code

You are incrementing $i before you do your conditional check; whereas; it should be done after your break statement. Although $i is set to 0 before you begin your loop, you immediately increment by 1 with your statement $i++; thus, when $var is 10, $i which was 0 not become 0+1=1 and so forth.
