note Corion <p>[doc://map] takes a list and returns a new list. The new list is created by gathering the results of the codeblock. The codeblock is invoked one per item in the original list:</p> <c> use strict; use Data::Dumper; my @items = qw(1 2 3 4 5 6 7); my @new_items; # Make a copy of @items in a very inefficient way @new_items = map { $_ } @items; # Make a new list 2 3 4 5 6 7 8 @new_items = map { $_+1 } @items; # Make a new list of strings: @new_items = map { ">$_<" } @items; # Make a new list with all items appearing twice: # 1 1 2 2 3 3 4 4 5 5 6 6 7 7 @new_items = map { $_ => $_ } @items; # Make a new list with all items quoted: map { $dbh->quote($_) } @userArray </c> 640255 640271
