About Codecademy

var aboutUs = "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.";var aboutRyanZach = "Ryan Bubinski and Zach Sims were students at Columbia before they started to work on Codecademy. They've worked at NYC startups, given numerous lectures on topics in programming, and are now living in Silicon Valley.";
