As you have seen in the previous two recipes, the HTML and CSS editors have been greatly improved in Visual Studio and you'll be pleased to know that the JavaScript editor has also received a significant overhaul. With HTML and JavaScript being first-class choices for developing Windows Store apps, it's not really a surprise that this happened.

Within the HTML5 specification, the marquee tag is of course not valid, but thanks to Aaron Powell (http://www.aaron-powell.com/doing-it-wrong/marquee), we have a way to implement a marquee tag using JavaScript and jQuery. In this recipe, we will write a JavaScript script to emulate a marquee tag so that we can learn how the editor works.
