JavaScript is the assembly language of the web, and the first generation of higher-level languages built on top of that foundation has arrived. CoffeeScript is an exciting entry in this nascent field, embracing the best of JavaScript, extending it with collection operators, and wrapping it all in a more succinct, Ruby-ish grammar. CoffeeScript's benefits have proven so compelling that it is supported in the core of Rails 3.1. The presenter, David Kinney @dlkinney, will introduce CoffeeScript's core syntax, demonstrate how it is used in a Rails 3.1 project, and show examples of its use in real-world client and server projects.
