Traditional classes do not exist in JavaScript. They can be very useful in decomposing your code into reusable component-like blocks. This is especially true if you are used to working with classes in other languages.

In this section, we will look at defining classes with properties and methods, using class inheritance, and some of the hurdles we can run into when using CoffeeScript classes.
