Perform actions based on conditions

Cycle through every member of an array

var string[] items = ["sock", "pants", "shirt", "skirt", "scarf"];
 
print "<ul>";
foreach var string item ( $items ) {
    print "<li>$item</li>";
}
print "</ul>";

Cycle through every member of an associative array

var string{} fruits = {"apple" => "red", "lemon" => "yellow", "grape" => "purple"};
 
print "<ul>";
foreach var string fruit ( $fruits ) {
    var string color = $fruits{$fruit};
    print "<li>$fruit: $color</li>";
}
print "</ul>";

Group together multiple conditions
