A Slideshow is a script that presents a series of images that you can flip through, either forward or backward.
In this course, we will be using Slideshow to illustrate some of the commonly used design patterns.

Whenever you see this graphic within the course, an applet that explains or dissects some element of a design pattern will follow. Move your mouse cursor over the elements of the image outlined in red to display pop-up explanations.

Many of the terms used in the course are defined in a JavaScript glossary. The terms appear as italicized and underlined in the lesson text. Clicking a glossary term opens a pop-up window with the definition.
