How do I iterate over a list in Perl?

You can use a foreach loop to iterate over a list in Perl. For example: foreach my $item (@list) { print $item; }.

Can you explain how the foreach loop works?

Sure! The foreach loop goes through each element in the array or list, assigning it to a variable (like $item) for use within the loop.

What if I want to modify the elements while iterating?

You can modify elements directly by accessing them via their index, or by using a map function to create a new modified list.

Can you show me an example of using map for modification?

Absolutely! You can use my @new_list = map { $_ * 2 } @list; to create a new list with each element doubled.
