There's a way of implementing an eraser (other than using a white pencil?).
I'm using layering, I have an image below the canvas, so, if eraser paints white, the user is going to notice since the below image isn't solid white.

function eraser()
{
context.strokeStyle = "rgb(255, 255, 255)";
context.globalCompositeOperation = "copy";
context.strokeStyle = ("rgba(255,255,255,255)"); /* or */ context.fillStyle = "rgba(255,0,0,0)";
}
both worked in my case!
