Re^5: Hash versus chain of elsifs

[choroba]

    my %junksites = (
        "bollyinside.com",
        "www.bollyinside.com",
 ...
       "worldtrademarkreview.com",
        "www.worldtrademarkreview.com",
        );

Note that hash needs key and value pairs, so you're storing only the site names without www as keys; the www. prefixed ones are stored as values. Probably not what you want.

The fast way how to initialize the keys is

my %junksites;
@junksites{qw{ 
    bollyinside.com www.bollyinside.com
    ...
    worldtrademarkreview.com www.worldtrademarkreview.com }} = ();
