What is JavaScript

JavaScript is a new scripting language which is being developed by Netscape. With JavaScript you can easily create interactive web-pages. This tutorial shows you what can be done with JavaScript - and more importantly how it is done.

JavaScript is not Java!

Many people believe that JavaScript is the same as Java because of the similar names. This is not true though. I think it would go too far at the moment to show you all the differences - so just memorize that JavaScript is not Java.

Running JavaScript

What is needed in order to run scripts written in JavaScript?.......more

You need a JavaScript-enabled browser - for example the Netscape Navigator (since version 2.0) or the Microsoft Internet Explorer (MSIE - since version 3.0). Since these two browsers are widely spread many people are able to run scripts written in JavaScript. This is certainly an important point for choosing JavaScript to enhance your web-pages.

Of course you need a basic understanding of HTML before reading this tutorial. You can find many good online ressources covering HTML. Best you make an online search for 'html' at Yahoo in order to get more information on HTML.
