Catalyst is a web framework that help you to do very many things automaticly without needing to write Perl code, but most of the things you will do in a Catalyst-based app are done by other Perl modules that you can get from CPAN. Catalyst can do the authentication, authorization, UTF-8 encoding, caching, generate JSON data, ease the use of templating systems like Template-Toolkit, use of different ORMS like DBIx::Class, or form processors like HTML::FormFu. It can also help you to use javascript (just search for "Catalyst javascript" on search.cpan.org). But Catalyst it can do very many other things. Passing from simple CGI scripts to use of Catalyst is a very good idea and Catalyst is not hard to learn, but it may be harder to learn to use other modules which are recommended to be used nowadays. In order to understand better what you will see in the Catalyst books and tutorials, it might be helpful to learn a little other modules before. For example: DBIx::Class, Template-Toolkit, HTML::FormFu. If you are also interested in using javascript in your apps, you may be interested in using REST and JSON. There are Perl modules on CPAN that can help you to have the javascript code wrote automaticly by those modules, but they are not recommended because it is better to learn how to use some javascript libs like jQuery, ExtJS, YUI, DOJO and so on. Those JS libs are better maintained and improved and they offer a bigger flexibility. But it is not compulsory to use javascript in your Catalyst apps. Catalyst is just a thin glue that let you use easier other modules from CPAN. It is not a CMS that generates javascript code for you, and even though it can let you use other Perl modules that do this, as I said, it is not recommended to do it if you care about maintaining and improving the apps for a long term.
