Introduction The Netscape Browser includes a scripting language called JavaScript that makes certain tasks in HTML much easier. JavaScript follows in the footsteps of other scripting languages like PERL, providing an interpreted text programming language that is easy to use and fairly rich. In many cases you can accomplish simple tasks in JavaScript that would take much more effort to accomplish in Java. It is therefore useful to know both Java and JavaScript so that you can appropriately use one or the other. Netscape provides on-line JavaScript documentation that is extremely good. If you read through the entire collection of material once (a task that takes about two hours), you will know just about everything there is to know about JavaScript. Rather than duplicate that effort, here are four simple examples that demonstrate how you might use JavaScript yourself.
