We can find the script debugger from the Sources tab of the fix javascript error developer tools. It'll look something like this: click to enlarge We've got a lot of stuff in this view. In this article, we'll be only focusing on breakpoints and stepping through the code, which can be found on the right. These are the main features of the debugger, and all the other functionality builds on top of them. A typical debugging scenario What happens in a typical situation when there's an error in your JS code? It causes an exception to be thrown. The first thing we want to do is to make sure we have "Pause on exceptions" enabled, which is the button on the right with the pause icon in it By enabling break on exception, Chrome automatically pauses code execution into the debugger for us if there's a problem. When this is enabled, we can also optionally make Chrome pause on caught exceptions. This means that every exception that is thrown results in Chrome pausing the execution.
