At the start of this year, I sat down to write the "Errors and Debugging" chapter of Simply JavaScript. I cracked my fingers, dove into the landscape of JavaScript debugging tools, and emerged very disappointed several hours later. At the time, Firefox was the only browser with a JavaScript debugging tool worth writing about: Firebug. Less than a year later, the landscape has changed dramatically. Every major browser has introduced new development tools that make it easier to diagnose problems with your HTML, CSS, and JavaScript code right inside the browser in question. But can any of these tools stack up against the slick and effortlessly powerful tools provided by Firebug? Let's take a look.

Welcome! In this tutorial, we're going to create a breakout clone that you can play in your browser, using javascript and the element. In order to use this tutorial, you'll need to have a relatively recent version of Firefox, Safari, or Opera. You cannot use Internet Explorer, because Microsoft hss decided not to implement the element in it. Before you read any further, click on the "run code" button on the left to play the game that we'll end up creating. On every page, you'll be able to click the "run code" button to run the code we've developed so far. Every page besides this one has an editor in it containing the javascript code that will be run in the same box as the game as soon as you click the button. You can make changes to the code, and see the results instantly by clicking the "run code" button. In order to make our lives easier, I've included the jQuery framework in every page, which extends javascript in your browser with some useful methods. If you have any comments or questions, feel free to leave a comment on the "comments" tab.
