MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

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 returns a Promise which resolves once the animation has finished playing.

Every time the animation leaves the finished play state (that is, when it starts playing again), a new Promise is created for this property. The new Promise will resolve once the new animation sequence has completed.

Syntax

var animationsPromise = Animation.finished;

Value

A Promise object which will resolve once the animation has finished running.

Examples

The following code waits until all animations running on the element elem have finished, then deletes the element from the DOM tree:

Promise.all(
  elem.getAnimations().map( 
    function(animation) { 
      return animation.finished 
    }
  )
).then(
  function() {
    return elem.remove();
  }
);
