New course: Make interactive webpages with JavaScript

On Khan Academy, our two most popular programming courses are Intro to JavaScript, where you learn the fundamentals of JavaScript with the ProcessingJS library, and Intro to HTML/CSS, where you learn to create, style, and lay out a web page. But that's like having strawberries and chocolate in front of you, and not dunking a strawberry in the chocolate.

Why? Well, JavaScript was originally invented in order to bring HTML/CSS web pages to life, to make them interactive with events and animation. The language has become very popular since its invention and is now used outside of browsers, but still today, it is the only language that browsers natively understand and it is used by every interactive web page on the internet.

That's why we've put together a course on making web pages interactive -- combining your knowledge of HTML/CSS with your knowledge of JavaScript so that you can programmatically access parts of your page and modify them in response to all sorts of user events. With that knowledge, you can make slideshows, games, galleries, apps -- virtually anything you've seen on the web.

Get started with the welcome video and HTML/CSS/JS review quizzes, then get deep into DOM access, modification, events, and animation.

A big thanks to our early reviewers for all their great feedback:
Nicholas Zakas, Kevin Lozandier, @wbwalp, @SpongeJR, Katarina L., and @TheSwedishHutt. Now go make your webpages fly!
