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.finished read-only property of the Web Animations API allows you to return the finished state of the animation so that further code can be run after it has finished.

Note: The Promise is replaced with a new (pending) Promise object every time the animation leaves the finished play state.


var animationsPromise = animation.finished;


A Promise object.


The following code waits until all animations have finished before removing the element they are active on:

    function(animation) { 
      return animation.finished 
  function() {
    return elem.remove();
