// image url
const url = "images/img.jpg";

// create image
var image = new Image();
image.src = url;

// waiting image load
image.onload = () => {
    // convert image to gray scale
    editpix.toGrayScale(image)
        .then(grayScaledImage => {
            // render original image
            document.body.appendChild(image);
            // render modified image
            document.body.appendChild(grayScaledImage);
        })
        .catch(error => { console.log(error) })
};
