Codecademy

“Codecademy was created out of the frustrations Zach and Ryan felt with learning how to program. Tired with less effective text and video resources, Ryan and Zach teamed up to create Codecademy, a better, more interactive way to learn programming by actually coding. This is just the beginning. Join us as we make it easy for everyone to love and learn how to code.”
