#Javascript experts, I need advice. I'm trying to extend a class in order to override a method or two. It defines everything in its constructor, and I can't work out how to use anything in the original class from my new one.
Could anyone suggest to me how syntactically I should minimally replace onKeyDown and handleKeyDown with my own versions, while still being able to use functions and properties from the base class? I'd really appreciate the guidance!
