While / Until

While Loops

A while loop runs as long as its condition is true:

my $i = 1;
while ($i <= 5) {
    say $i;
    $i++;
}

Until Loops

until is the opposite of while -- it runs until the condition becomes true:

my $count = 0;
until ($count == 3) {
    say $count;
    $count++;
}

Increment / Decrement

$x++;   # increment by 1
$x--;   # decrement by 1
$x += 5;  # add 5
