Submodule 15.1: Canvas HTML element

We need CanvasRenderingContext2D to create a surface in which we can draw on.

The steps to use CanvasRenderingContext2D are:

var canvas0 = document.getElementById("mycanvas0");
var context0= canvas.getContext('2d'); 
/* context0= will be your context */

You only need to do this once and then you can keep using it to do all your drawing.

In the next lesson, we will use this surface to start drawing.
