{{APIRef("Web Animations")}}

The Animation.reverse() method of the {{ domxref("Animation") }} Interface reverses the playback direction, meaning the animation ends at its beginning. If called on an unplayed animation, the whole animation is played backwards. If called on a paused animation, the animation will continue in reverse.

Syntax

reverse()

Parameters

None.

Return value

None ({{jsxref("undefined")}}).

Examples

In the Growing/Shrinking Alice Game example, clicking or tapping the bottle causes Alice's growing animation (aliceChange) to play backwards, causing her to get smaller. It is done by setting aliceChange's {{ domxref("Animation.playbackRate") }} to -1 like so:

const shrinkAlice = () => {
  // play Alice's animation in reverse
  aliceChange.playbackRate = -1;
  aliceChange.play();

  // play the bottle's animation
  drinking.play();
};

But it could also have been done by calling reverse() on aliceChange like so:

const shrinkAlice = () => {
  // play Alice's animation in reverse
  aliceChange.reverse();

  // play the bottle's animation
  drinking.play();
};
