JavaScript met and, indeed, exceeded these requirements by providing an extremely flexible and easy to learn scripting language. The problem today is that, as with any useful technology, it has been used in ways never anticipated by its original authors. As a result the potential uses of JavaScript have grown far beyond the needs of the average person with aneed to add dynamic behavior to web pages. The result of this is that JavaScript book authors also feel the need to cover every possible capability of JavaScript to the extent that a typical JavaScript reference now runs to over 1,000 pages.
The purpose of this book, therefore, is to provide the essentials of JavaScript so that anyone with a web site can use this powerful scripting language quickly and effectively without having to learn things that , whilst within the capabilities of JavaScript, aren't actually needed by the average web designer.
