Slides from a talk I gave at RailsConf 2011 yesterday morning.
A major theme of the conference was rediscovering JavaScript (in part by using tools like CoffeeScript that make the language more palatable to Rubyists). I wanted to talk about what may be the next stage of that: Running the same code on both the front end (in the browser) and the back end. I gave an example of using this technique for form validations, which is great when there's complex validation logic that you don't want to write twice in two different languages.
