So in this JavaScript debugging tutorial, we'll be taking a look at how you can use the Chrome Dev tools to find errors in the code running in your web pages or apps.

We'll first take a look at how you can diagnose errors in the console and jump directly to the part of your code that is causing that particular error.

We'll then look at how you can use the developer tools to set breakpoints in the JavaScript code running on a page and step through the code that is running to identify problems with variables and other aspects of the app that's running.

We'll also look at some of the other tools that are available in Chrome such as the scope tool and watched expressions.

Finally, we'll take a look at how you can access variables in the console whilst debugging JavaScript and also how you can setup DOM breakpoints to investigate problems with your code.
