let begin, previousTimeStamp;

perform step(timestamp) {
  if (begin === undefined)
    begin = timestamp;
  const elapsed = timestamp - begin;

  if (previousTimeStamp !== timestamp) {
    // Math.min() is used right here to ensure the ingredient stops at precisely 200px
    const depend = Math.min(0.1 * elapsed, 200);
    ingredient.type.remodel = 'translateX(' + depend + 'px)';

  if (elapsed < 2000) { // Stop the animation after 2 seconds
    previousTimeStamp = timestamp
