That leap wasn't easy. My first real project was a simple video game using jQuery animations and I had to spend a lot of time going over my completed Codecademy lessons, using the Codecademy lab, and just searching Google till I wanted to tear my hair out. Slowly though, one feature at a time, I got my game working. Then I went on to even more challenging projects.
Today I can code in all the languages above plus several other languages. I write apps as part of my job in information technology and I've written everything from network utilities to a speed test clone to an inventory tracking system built from scratch. I've taken freelance clients and I run a local coding group (www.codeslo.com) with over five hundred members, where I teach web development for free to anyone who wants to learn. Codecademy is, of course, part of our curriculum.
So, basically, you guys rock. Without Codecademy I honestly do not know if I would have been successful learning to code. I can't wait to see what you do with your new courses.
