html5 canvas: overlapping paths not filling correctly - html5-canvas

Question

strange issue with HTML5 canvas: I am trying to draw one shape inside another. The outer shape is blue and the inner one red, but the end result is that both shapes end up red. If I step through the code, I can see the blue shape rendered correctly, but then the red shape renders over the blue one, even though it's smaller. Probably a problem with BeginPath/EndPath stuff, but I've seemingly tried every combination with no luck. I have lots more shapes to draw after this one, so I need to figure out how to correctly begin/end a shape before I resume work. Any help is appreciated.

Answer 1

context.beginPath;
...
context.closePath;
You forgot (). Without that, these are just discarded references to a function, not calls to it.
