For / Foreach

For Loops

Perl's for loop can iterate over a range:

for my $i (1..5) {
    say $i;
}

The 1..5 range operator produces the list (1, 2, 3, 4, 5).

Foreach

foreach iterates over a list or array:

my @colors = ("red", "green", "blue");
foreach my $color (@colors) {
    say $color;
}

In Perl, for and foreach are interchangeable:

for my $color (@colors) {
    say $color;
}
