In this repl, I have an error, saying Ball isn't a constructor. What does this mean and how can I fix it?

This only draws half a canvas. @Coder100

Coder100 (16904)

make sure your logic is correct lol @WilliamXing

Coder100 (16904)

lol you set the height to make it half the canvas

see the ball now @WilliamXing

Why does the ball fall off the canvas? @Coder100

Coder100 (16904)

because you set the canvas height too low remember
look in the repl it works @WilliamXing

You accidentally put all the prototype methods inside of another function.

To not make these mistakes, declare the methods immediately after the function.
