Now that we're comfortable with building and maintaining complex CoffeeScript applications, we're ready to start working on real-world systems. Often, this means integrating CoffeeScript into another framework. You may have an existing project that you'd like to use CoffeeScript in, or you may be looking to start a new project with...
