1) Does all javascript focus on displaying things on a canvas?
2) Can I have help with collision detection involving rectangles
and circles? I know how to find if a certain point has collided
with a circle ["if(dist(x1, y1, cirlceX, circleY) < circleSize /
2) {...}"] but I don't know how to tell if an entire rectangle
has collided with a circle, unless I write an incredibly large
amount of code.
