function getAspectRatio(imageSrc) {
  const img = new Image();
  img.src = imageSrc;

  return new Promise((resolve, reject) => {
    img.addEventListener("load", () => {
      const aspectRatio = img.naturalWidth / img.naturalHeight;
      resolve(aspectRatio);
    });

    img.addEventListener("error", (error) => {
      reject(error);
    });
  });
}

// Example usage:
const imageSrc = "https://example.com/image.jpg";
getAspectRatio(imageSrc)
  .then((aspectRatio) => {
    console.log("Aspect ratio:", aspectRatio);
  })
  .catch((error) => {
    console.error("Error:", error);
  });
