Debugging JavaScript: Understanding JavaScript Error Messages

Debugging JavaScript: Understanding JavaScript Error Messages: "One of the most pervasive criticisms about JavaScript is that it's painfully difficult to debug. Some shops (mine included) have gone to great lengths to minimize JavaScript code by transferring functionality to the server and using Ajax to feed values and properties back to the page. That's a reasonable solution for large applications, but it's a lot of overhead for smaller websites. The good news is that you don't have to be intimidated or turned off by JavaScript. There are plenty of ways to ferret out even the most obscure bugs, from writing your own tracing functions to developing in full-featured IDEs. In this article, we will be taking a look at the types of errors that you are likely to encounter in JavaScript development and how to minimize the chance of them cropping up in your code."
