This app offers a lot of quality problems to complete. It gives plenty of opportunity to code, and touches on important concepts. A few problems say I didn't pass some of the tests, but the code gives the correct answer when I run it on another code editor or even the app's playground. Still, even in these situations, I learned a lot by testing code, tweaking it, and running code again.

Thank you for your feedback! Can you give me an example of a solution, that is correct, but don't pass a JS Hero test? So I can fix that test. My email is on the contact page.

This is a great app. Not for beginners though. If you don't know how to code, stay away. This app doesn't quite cover all concepts but since other apps don't either, I still learned stuff. A very good job of explaining stuff I wasn't to clear on before. I also love the navigation system. I wish you could save your code that you write in the code playground. Note: my progress and playground code is randomly deleted. This is annoying but you can jump to lessons(not start at beginning).

really good app. For strenghtening skills mostly. It seemed a bit basic for me :) I wait for kind of advance version wit jquery and some graphics coverage eventualy css, node.js or similar. design is bit cheap, and when quit always starts from lession 1, but like the whole way it is constructed.Keep up!
