How do I enable JavaScript?
Posted by James Robshaw on 30 July 2007 12:29 PM

JavaScript is a programming language for the World Wide Web. JavaScript programs are downloaded along with Web pages and run on your computer. Web programmers can include JavaScript programs to make using their Web pages easier. JavaScript can enable links, edit data, help you fill in forms, and do many other useful things. Most complex sites, like Internet e-commerce and banking sites, use JavaScript.

JavaScript is fundamentally safe. The programmers who designed JavaScript deliberately omitted the ability to write to your disk or do other things that could damage your computer. JavaScript has been abused to open unwanted windows or change the page you're viewing in unwanted ways. These things are annoying, but not truly damaging. Modern browsers intercept and prevent the worst of the annoyances.
