requestanimationFrame JS

/* Tells the browser that you wish to perform an animation and 
 requests that the browser call a specified function 
 to update an animation before the next repaint. */

requestAnimationFrame(() => {
    // some animation-related/dependent code here
});

/* The callback function is automatically passed a timestamp 
 indicating the precise time requestAnimationFrame() was called at.
 requestAnimationFrame() returns a non-zero integer that can be passed into 
 cancelAnimationFrame() to cancel a requestAnimationFrame() call */

/* Advantages over setTimeout(..., 1000/60) approach:
 - The browser can optimize it, so animations will be smoother
 - Animations in inactive tabs will stop, allowing the CPU to chill
 - More battery-friendly */

Coding is fun

requestanimationframe

const element = document.getElementById('some-element-you-want-to-animate');
let start, previousTimeStamp;

function step(timestamp) {
  if (start === undefined)
    start = timestamp;
  const elapsed = timestamp - start;

  if (previousTimeStamp !== timestamp) {
    // Math.min() is used here to make sure the element stops at exactly 200px
    const count = Math.min(0.1 * elapsed, 200);
    element.style.transform = 'translateX(' + count + 'px)';
  }

  if (elapsed < 2000) { // Stop the animation after 2 seconds
    previousTimeStamp = timestamp
    window.requestAnimationFrame(step);
  }
}

window.requestAnimationFrame(step);
