#3. JAVASCRIPT

다음은 JAVASCRIPT 코드 입니다!

const wrap = document.querySelector('.wrapper');
  const eye = document.querySelector('.eye');
  const speed = 1;
  let x = 0;
  let y = 0;
  let followX = 0;
  let followY = 0;
  function animate() {
    x += (followX - x) * speed;
    y += (followY - y) * speed;
    eye.style.transform = `translate(${-x}px, ${-y}px)`;
    wrap.style.transform = `translate(-50%,-50%) perspective(600px) rotateX(${-y}deg) rotateY(${-x}deg)`;
    requestAnimationFrame(animate);
  }
  window.addEventListener('mousemove', (e) => {
    let mouseX = Math.max(-100, Math.min(100,window.innerWidth / 2 - e.clientX));
    let mouseY = Math.max(-100, Math.min(100,window.innerHeight / 2 - e.clientY));
     followX = (12 * mouseX) / 100;
     followY = (10 * mouseY) / 100;
  });
  window.addEventListener('keydown', (e)=>{
    switch(e.keyCode) {
      case 37:
        followX = 12;
        break;
      case 38:
        followY = 10;
        break;
      case 39:
        followX = -12;
        break;
      case 40:
        followY = -10;
        break;
      default:
        break;
