I am planning to purchase the new sitepoint Ruby on Rails book. I took a look at the article on the main page and read most of it, however I didn't see why ruby is so beneficial.

Aperantly it reduces code because it incorporates a variety of libraries used for database connectivity, AJAX, and so on.

I am not entirely sure on if this is correct (I have never used the framework before) so could someone please explain the primary benefits of the ROR.

Thanks
