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.
(1) No--javascript is a thing apart that has access to things in the DOM, like a canvas element. It really doesn't care if such things as a canvas element even exists.
(2) Yes- you might have to write an incredibly large amount of code.
