I know JavaScript fairly well but I want to learn another language. I'm pretty much set on learning Ruby but if you think I should learn another language, feel free to add your opinion.
What books/websites/tutorials do you guys think I should have a look at to learn Ruby?
Edit: I'm also looking to learning Rails and Sinatra in addition Ruby
"The Ruby Koans walk you along the path to enlightenment in order to learn Ruby. The goal is to learn the Ruby language, syntax, structure, and some common functions and libraries. We also teach you culture by basing the koans on tests. Testing is not just something we pay lip service to, but something we live. Testing is essential in your quest to learn and do great things in Ruby."
