I previously thought that using canvas api would better the performance of the canvas. Turns out that it is not true. Adjusting scale, transform with canvas api actually harms performance than actually calculating the position and rendering it. https://stackoverflow.com/questions/41060789/html5-canvas-transform-vs-manual-offsets Seems like we need to stick to the current version of calculating the positions and then rendering it on the canvas!

Plus I also found a meaningful MDN article from mozilla on optimizing canvas. TLDR; It says that you should use multiple canvas if you are going to separate logic. Also you should consider using adequate canvas apis such as clearing the canvas with clearRect() instead of fillRect().

I also found a Firefox article that goes into more depth on how to optimize your canvas. It says that you should use webgl instead of contex2d since webgl allows you to use GPU.
