Benchmark: Canvas context2d: Image vs ImageBitmap vs Canvas

Script Preparation code:

var img = new Image();
var imageBitmap;
var doneLoading = false;
let canvasImage = document.createElement('canvas');
canvas.width = 640;
canvas.height = 480;
let canvasImageBitmap = document.createElement('canvas');
canvas2.width = 640;
canvas2.height = 480;
let canvas = document.createElement('canvas');
canvas2.width = 640;
canvas2.height = 480;
let canvasCanvas = document.createElement('canvas');
canvas2.width = 640;
canvas2.height = 480;

var ctxImage = canvasImage.getContext('2d');
var ctxcImageBitmap = canvasImageBitmap.getContext('2d');
var ctx = canvas.getContext('2d');
var ctxCanvas = canvasCanvas.getContext('2d');

img.addEventListener('load', function() {
  Promise.all([
    createImageBitmap(img)
  ]).then(function(images) {
  imageBitmap = images[0];
  doneLoading = true;
}, false);
});

if (doneLoading) {
  ctx.drawImage(img,0,0)
}

img.src = 'https://1.bp.blogspot.com/-52MtzD0GfX0/WvP52CL1WjI/AAAAAAAAOVw/_OpK4JHeWK01d-7IiZ6vzojYGhXqLRXrACLcBGAs/s1600/EMxediL.jpg';

Tests:

Image
if (doneLoading) ctxImage.drawImage(img,0,0);
ImageBitmap
if (doneLoading) ctxImageBitmap.drawImage(imageBitmap,0,0);
Canvas
if (doneLoading) { ctxCanvas.drawImage(canvas,0,0) }
