Learning how to use CoffeeScript and how to use it well is not enough. It’s necessary, but it’s not sufficient. Why? Because the applications you write using CoffeeScript exist in a real world with practical considerations beyond the language itself. This part of the book prepares you for writing robust and maintainable applications in CoffeeScript both today and in the future.
Because this part explores topics that are ancillary to CoffeeScript, it takes the time to also teach the underlying concepts in those topics. Depending on your familiarity with the focus of each chapter, you should adapt your reading style accordingly.
