How can I make one single ball to move around?

Question

Sorry about the question. Maybe it can be basic, but just knew about p5 and I ran off to my computer, watched the main tutorial on p5's official page and came out with that idea. Is there a way to erase every draw? Or is it another way to do it? I'd appreciate the help you can offer me.

Sorry though, my implementation is in pure Javascript
