Some errors pop up when you press reset and characther length.
Some warnings are also in the code that werent in the real app
There are also errors when you run the code.
I tried to make a projects page tgat stored my projects. I started with my code runner (the app in the error)
But it wasnt really smart (enough)
So then people would be sad because they cant interact!
