회고

JS 강의를 끝내고 HTML과 JS를 이용해 간단한 Todo웹사이트를 만들었다.
아직 CSS는 어려워서 디자인은 나중에 다시 손볼 예정이다.
오늘치 데일리 미션도 끝냈다.

오늘 배운것

background.js

const images = [
  "0.png",
  "1.jpg",

  "7.jpg",
];

const chosenImg = images[Math.floor(Math.random() * images.length)];

const backgroundImg = document.createElement("img");

backgroundImg.src = `img/${chosenImg}`;

document.body.appendChild(backgroundImg);

clock.js

const clock = document.querySelector("h2#clock");

function getClock() {
  const date = new Date();
  const hours = String(date.getHours()).padStart(2, "0");
  const minutes = String(date.getMinutes()).padStart(2, "0");
  const seconds = String(date.getSeconds()).padStart(2, "0");
  clock.innerText = `${hours}:${minutes}:${seconds}`;
}
getClock();
setInterval(getClock, 1000);
