Ranked in these QuestionsQuestion Ranking
Pro Excellent progression
Codeacademy doesn't overwhelm beginners with information. It gives bite-sized information, the bare minimum needed to finish a task and get to the next one. As the course progresses, it slowly fills in background information.
Right from the start, users write code. They start small in an environment that has constant feedback and gradually progress to more complex concepts. Users can see code results instantly, giving great feedback.
Pro Bite-sized lessons
Each lesson in code-academy focuses on a single concept, and repetition is provided to drill the concept.
Pro Good editor
Codeacademy has a powerful, beginner-friendly integrated development environment (IDE) that can also be used outside of curriculum.
Codecademy does not offer pro/paid accounts. Instead, all of their content is available entirely for free.
Con Lack of context
Codecademy is great for providing a hands-on approach, but there is a lack of context regarding how to start a project in real life. While users may learn how to code using Codecademy's interface, they may not have any idea how to code independently.
Codecademy is known to have many bugs which interfere with the editor, resulting in error messages despite having the correct answer.
Con Allows infinite loops to run
If you run an infinite loop, the browser freezes. Many other similar websites will give you an error, preventing the loop from running. Though not a bug, the lack of feature to stop infinite loops from running can be quite frustrating to beginners.
Con Not the best structure for quick refreshers
The content of the lessons is aimed very much at people just starting to learn how to code. This is perfect for beginners but if you want to use Codecademy to refresh your knowledge the lessons are not designed to be quickly done.
