Hello, 
my   question : Should I use plain Canvas to make html/js game or should I use some library like kinect.js?

I started developing with plain canvas   but I noticed that it takes kid of much time to add event onclick on canvas element, but generally what are advantages and disadvantages of using libraries for  canvas and plain canvas?
