Welcome to Learn JavaScript in a Weekend. This book will teach you everything that you need to know to get started using this exciting and fun Web scripting language. By the time the weekend is over, you'll be ready to update your Web site to make it a lot more interactive and entertaining for your visitors . This book also will teach you how to create scripts using JScript (which is Microsoft's version of JavaScript) to automate all sorts of tasks on Windows operating systems.

In this chapter you will learn the background information that you need to know about JavaScript. This will include learning where it came from, what browsers support it, and the steps involved in creating and testing your JavaScripts.

To develop JScripts that run directly from the Windows desktop, you'll also need to learn about the Windows Script Host (WSH). This chapter will explain the WSH's basic architecture and show you how to configure it and use it to run your first JScript. By the time you go to bed tonight, you'll have the foundation you need to finish the rest of this book and begin your journey as a JavaScript and JScript programmer.
