possibly offtopic but as a non-beginner javascript developer I find some things taught to be not best practices. its possible that the user is being guided up to a place where he fully understands "this is why this method is better". an obious example is the use of global variables and functions whose main purpose is to act on global variables. while not technically wrong, it is definitely a no no in modern development. From what I went through I would say its a good platform to learn syntax and keyword definitions e.g. "this is a function" but it doesnt address the application part. and no having a step by step project at the end of the lesson does not address the application part. application needs to teach how to think in programming, how to take problems conveyed in english and solve them with programing. lastly, ive found technical errors in the way instructions are worded. what they are asking for in english is not exactly what they expect as the code solution. needless to say this frustrates beginners. its very hard to teach.
