It's not very intuitive, but after some tries I could make a function and evaluate it. :)
* Perhaps avoid function with more than one expression in the body. Since this has no side effect, then two expressions in the body is confusing.
* Perhaps add a frame in the side to evaluate any function with any argument. The trick to make a last function just to evaluate it is fine, but a way to evaluate it on the side is easier to understand.
* When I have to choose which function to call I get "*(a b)" instead of "(* a b)", but later I see the second way to write it.
* I closed the window and now I don't see any predefined function. Refreshing the page a few times fixed this, but I still can't use it. Using private mode fix the problem, so I guess there is something wrong in the cookies.
This is a toy project and this is only a beginning. The goal is to have a sandbox where you can write some functions without installing additional software.
