Answer 1

Calling your class Object is not a good idea since it's a built in keyword in javascript and this was causing some confusion.

also, the line this.result() = result; is incorrect, you do not need to declare functions in the constructor.

I fixed your code in here, I hope this helps :)

Answer 2

It's your line with this.result. You can comment it out.
