It’s the only type that can point to another website. • Root-relative paths are good for JavaScript files stored on your own site. Because they always start at the root folder, the URL for a JavaScript file will be the same for every page on your website, even when web pages are located in folders and subfolders on your site. However, root-relative paths don’t work unless you’re viewing your web pages through a web server—either your web server out on the Internet, or a web server you’ve set up on your own computer for testing purposes.

So how do you figure out what’s gone wrong? There are many ways to track errors in a JavaScript program. You’ll learn some advanced debugging techniques in Chapter 17, but the most basic method is to consult the web browser. Most web browsers keep track of JavaScript errors and record them in a separate window called an error console. When you load a web page that contains an error, you can then view the console to get helpful information about the error, like which line of the web page it occurred in and a description of the error.
