The suggested starting point is Web Fundamentals (HTML and CSS). Now, it’s been awhile since I’ve coded in either of these languages but back in middle school I was a pretty big web design geek. In those days, if you could write your entire site’s CSS in a .txt file, upload it and have it work, that got you street cred… web cred? Whatever. Point is, I thought a review might be fun but after completing the first course I moved onto something a little more challenging.
All in all I had a productive afternoon filled with learning. Although I’ve never taken a university computer science class before, I’m guessing this is a pretty good alternative. If you’d like to share your own experience using Code Academy, feel free to do so in the comments!
