As an effect of developments in the World Wide Web, it so happens that every computer equipped with a modern web-browser also has an environment for programming JavaScript. In today's spirit of not bothering the user with technical details, it is kept well hidden, but a web-page can make it accessible, and use it as a platform for learning to program.
Besides explaining JavaScript, this book tries to be an introduction to the basic principles of programming. Programming, it turns out, is hard. The fundamental rules are, most of the time, simple and clear. But programs, while built on top of these basic rules, tend to become complex enough to introduce their own rules, their own complexity. Because of this, programming is rarely simple or predictable.
