It's building block method of instruction makes it great for beginners, and those completely new to computer code. While the app version is extremely lite, the robust website offers lessons in jQuery, JavaScript, PHP, Python, and Ruby.

Some activities simply ask users to read and understand, while other require users to apply what they learned. The app version is particularly user friendly, and boasts an "Hour of Code" where users are provided with examples of code and in turn learn how it works and powers the web. Due to the sometimes complex nature of computer coding, Codecademy is best suited for children ages 8 and older.
