my program displays images using forEach. I want to replace it with for

  images.forEach((img, ind) =>  {
    const oImage = new Image();
        oImage.onload = () => 
        {
          ctx.drawImage(oImage, ind * 100, 0, 100, 100);
        };
    oImage.src = img.textContent;
  }
  );
}

  • @stargatesg1 I recommend you to study the use of forEach since it could be more easier to use than a traditional for. See the different ways [you can iterate over an array](https://stackoverflow.com/a/3010848/7927192) – ricardo-dlc Oct 24 '20 at 17:47

I don't understand why you want to get rid of forEach, but you have the answer and it's simple as this:

for (let i = 0; i < images.length; i++) {
  const oImage = new Image();
  oImage.onload = () => {
    ctx.drawImage(oImage, i * 100, 0, 100, 100);
  };

  oImage.src = images[i].textContent;
}
