This chapter provided samples for a couple of common tasks that are used in web development: tables and lists, field completion, and even a generic frame, called a dynamic user interface, for our sample code. Both the tables and lists sample and the field completion sample had a very simple CSV-based "database" that holds the data for our purposes, and both had a remoted method that DWR uses to get the data from the server and show it in the client.

We also saw some good examples of HTML, CSS, and JavaScript. In fact, without knowledge of JavaScript it would be difficult to write web applications.
