Chapter 28. Debugging Your Code > Troubleshooting JavaScript

Troubleshooting JavaScript

Although JavaScript is not a true programming language like Java (see the sidebar "What Is the Difference Between Java and JavaScript?" in Chapter 27), you still must use logic to construct the actions that should take place. Things inevitably go wrong.

Unlike CSS, though, JavaScript does not require you to eyeball the code to figure out what's wrong. Most browsers display an error message that details what went wrong and where.
