problems. No matter how hard I try, there's always something that needs debugging. In the past, I would use console.log or alert. Just sprinkle them in my code, and hope that they give me enough information to fix the problem. If you've tried doing that, you know that it's not a very good approach. It's like giving a surgeon a machete instead of a scalpel - not accurate and a bad tool for the job. But just like surgeons have scalpels, we have better tools available for us too: Namely, debuggers. In this article, I'll show you how to make use of Chrome's JavaScript debugger to help you fix errors faster and more easily. Getting started To get started, we can open up the Developer Tools either through the menu, by right clicking the page and choosing "Inspect Element", or by pressing F12 (or Cmd+Opt+i if you're on a Mac). We can find the script debugger from the Sources tab of the 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. It can sometimes be useful if the error is being handled by a library, and Chrome won't pause on it. Inspecting values When Chrome pauses script execution, we can get a lot of information on what's going on. This is one of the big benefits of using the debugger - you get access to everything the script had access to. No need to add random logging and try to guess what went wrong. In the code view, Chrome gives us readouts on variable values. The line highlighted in blue is where the code is paused. The red icon on the line indicates an exception was thrown. We can see the error message either by hovering the cursor over
