My website review is going to be on I would give it 4 stars. It is a very nice website that teaches you how javascript works in a very simple and fun way.
You get to choose a hero as your character and you are allowed to change your character if you want to. It gives you hints on how to complete the level and gives you a set of commands to use to complete the level such as: hero.moveLeft(), hero.moveUp(), hero.moveDown(), hero.moveRight(), hero.Attack(). The only thing that it doesn't teach you is what goes on. It shows you the code and how if works and what goes first but it doesn't show you how it calls an event. Other than that it goes over the basics of how javascript works.
