This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The Animation.reverse() method of the 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.





Return value



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 Animation.playbackRate to -1 like so:

var shrinkAlice = function() {
  // play Alice's animation in reverse
  aliceChange.playbackRate = -1;;
  // play the bottle's animation

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

var shrinkAlice = function() {
  // play Alice's animation in reverse
  // play the bottle's animation
