Admin Template xf:if explanation

[silence]

In the ban edit admin template, there is this snippit:

        <xen:snippet>
            {xen:if {$bannedUser.user_reason}, '{xen:phrase reason}: <span class="muted">{$bannedUser.user_reason}</span>'}
            {xen:phrase ban_ends}: <span class="muted">{xen:if $bannedUser.end_date, {xen:datetime $bannedUser.end_date}, '{xen:phrase never}'}</span>
        </xen:snippet>

In the line here:

{xen:if $bannedUser.end_date, {xen:datetime $bannedUser.end_date}, '{xen:phrase never}'}

I'm extremely confused as to how that exactly works. Is it checking if $bannedUser.end_date is true?
Could someone be generous enough to explain that, I feel dumb

If there is an end date, show the formatted date, else display the phrase never.

Ah gotcha. I feel sorta dumb. Does it check if it's 0, false, null or just a single value?

It works the same as the PHP if function.

Yeah but those commas threw me off
Well I got it now so thanks

Syntax:

{xen:if (boolean expression), (true), (false)}

Translates to:

if (boolean expression) {
 (true)
} else {
 (false)
}
