window.addEventListener("keydown", (e) => {
  let container = document.querySelector("#container");
  let { key, keyCode, code } = e;
  let template = "";
  [
    {
      title: "e.key",
      content: key == " " ? "Space" : key,
    },
    {
      title: "e.keyCode",
      content: keyCode,
    },
    {
      title: "e.code",
      content: code,
    },
  ].forEach((item) => {
    template += `
${item.title}${item.content}
`;
  });
  container.innerHTML = template;
});
