Possibility of allowing multiple transform keyframes per property

Instead of just a to and from for each property, would you consider allowing multiple ‘keyframes’ in an animation?

Something like this perhaps

anime({
  targets: 'div',
  translateX: '13rem',
  rotate: [{
      value: 90,
      duration: 750,
      easing: 'easeInOutQuad'
    }, {
      value: 180,
      duration: 750,
      easing: 'easeInOutBounce'
    }
  ],
  scale: {
    value: 2,
    delay: 150,
    duration: 850,
    easing: 'easeInOutExpo',
  },
  direction: 'alternate',
  loop: true
});

So each part of the rotate array would happen in sequence. This just allows more complex animation curves to be created. Keen to make a PR if you are interested.

Awesome! I don’t see the value being an array to be an issue. If I’m not mistake, the current behaviour is that if you pass a value, it will animate from its current value to that new value? And if you pass a (2 element) array it will interpolate from the first to the last? So, I think it will still be the same logic.

It might even be possible to simply flatten the object in some way, where each element in the array becomes a new property but with altered delays.

That would allow you to use the same logic for total animation duration, playing, etc.

Would you accept a PR for this or would you rather take a look at it yourself once it’s a priority?

Yes this is definitively something that can be useful. I’m not sure how it will fits in the current API, because the value property can also accept an array. This is something I’ll consider 👍
