Just a thought about challenges

Question

I understand that they're supposed to be somewhat difficult, but some of them are difficult just because they use bad programming practices such as initializing multiple variables within the same class with the same name, or varying only by capitalization.

Of course the small layout on mobile doesn't help as formatting also gets messed up so that the code is harder to read.

And the fact that code is missing its syntax highlighting also makes it that much harder to mentally parse in limited time.
