It's basically Duolingo for coding. But if you're a complete newbie, it's not user friendly. It gives you an explanation on a certain type of function, only to then give you an excersise that is way more complex than the example that's given and impossible to solve with the explanations that were given. Even when using the hints or AI assistant, you are pretty much left in the dark. I deleted my account after two weeks, because I wasn't learning anything.
