How to use the ember-animated.parallel function in ember-animated

transition: function * ({ receivedSprites, sentSprites, removedSprites }) {
    printSprites(arguments[0]);
    // received and sent sprites are flying above all the others
    receivedSprites.concat(sentSprites).forEach(sprite => {
      sprite.applyStyles({
        'z-index': 1
      });
    });

    receivedSprites.forEach(parallel(move, scale));
    sentSprites.forEach(parallel(move, scale));

    removedSprites.forEach(sprite => {
      sprite.endTranslatedBy(0, 0);
      continuePrior(sprite);
      opacity(sprite, { to: 0 });
    });
  }

removedSprites.forEach(sprite => {
      sprite.endAtSprite(beacons.one);
      parallel(move(sprite, scale(sprite)));
    });
  },

moveThem: function*({ keptSprites }) {
    keptSprites.forEach(
      parallel(
        moveSVG.property('cx'),
        moveSVG.property('cy'),
        moveSVG.property('r'),
      ),
    );
  },

insertedSprites.forEach(sprite => {
       let connectionName = sprite.element.getAttribute('data-connection-name')
       sprite.startAtSprite(beacons[connectionName]);
       parallel(move(sprite, { easing: easeIn, duration: 500}));
     });
   },

transition: function*({ sentSprites }) {
    let motions = this.motions();
    sentSprites.forEach(parallel(...motions));
  },
}).reopenClass({

transition: function * ({ sentSprites }) {
    sentSprites.forEach(
      parallel(
        move,
        compensateForScale,
        adjustCSS.property('font-size'),
        adjustCSS.property('letter-spacing'),
        adjustColor.property('color')
      )
    );
  }
}).reopenClass({

keptSprites.forEach(sprite => {
      parallel(move(sprite), scale(sprite));
    });

insertedSprites.forEach(sprite => {
      sprite.startAtSprite(beacons.add);
      parallel(move(sprite, scale(sprite)));
    });

keptSprites.forEach((sprite: Sprite) => {
            parallel(
                fadeIn(sprite),
                move(sprite, { easing: easeIn }),
            );
        });
        removedSprites.forEach((sprite: Sprite) => fadeOut(sprite));
