Hello! I fixed this issue in different way:

window.onload = () => {
  init();
  animate();
};

hello i am getting this error at runtime

ERROR in ./src/js/canvas.js

Module build failed (from ./node_modules/babel-loader/lib/index.js):

Error: Cannot find module 'babel/preset-env'

hello, I have an error when I finish the 10.49 minute steps. My screen is all black and I get these errors, how do I solve it? Thanks

there is a problem with the return Promise code. Here's the error.

canvas.js:134 Uncaught TypeError: undefined is not a promise

at Promise (<anonymous>)

at createImageAsync (canvas.js:134:12)

at init (canvas.js:164:18)

at Module../src/js/canvas.js (canvas.js:320:1)

at __webpack_require__ (bootstrap:19:1)

at bootstrap:83:1

at bootstrap:83:1

and here's my code: function createImageAsync(imageSrc) { return Promise((resolve) => { const image = new Image() image.onload = () => { resolve(image) } image.src = imageSrc }) }

does anybody know what I did wrong?
