CoffeeScript offers more than nice syntax for setting and managing data and functions. It also offers Classes, Inheritance, access to a 'super' method, Ruby-style string interpolation, easy variable and function bindings, and chained comparisons.  Here’s the code I showed in the video: class Vehicle constructor: (@name) -> move: (miles) -> console.log @name + " drove " + miles + " miles." class VWBug extends Vehicle move: -> console.log "Cruisin'..." super 100 class Truck extends Vehicle move: -> console.log "Haulin'..." super 50 mater = new Truck "Mater" herbie = new VWBug "Herbie" mater.move() herbie.move() a1c = "7.6" healthy = 7.0 > a1c > 5.0 console.log "A1C within healthy range: #{a1c}" Account = (customer, cart) -> @customer = customer @cart = cart $('.shopping_cart').click (event) => @customer.purchase @cart If you're new to CoffeeScript, make sure you check out the CoffeeScript Cookbook and CoffeeScript Basics.
