JavaScript, a programming language built into your web browser, is one
of the best ways to add interactivity to your website because it’s the only crossbrowser language that works directly with web browsers. Other languages
such as Java, Perl, PHP, and C don’t have direct access to the images, forms,
and windows that make up a web page.
JavaScript is also very easy to learn. You don’t need any special hardware
or software, you don’t need access to a webserver, and you don’t need a degree
in computer science to get things working. All you need is a web browser and
a text editor such as SimpleText or Notepad.
