HTMLElement: animationend event
The animationend
event is fired when a CSS Animation has completed. If the animation aborts before reaching completion, such as if the element is removed from the DOM or the animation is removed from the element, the animationend
event is not fired.

Examples
This example gets an element that's being animated and listens for the animationend
event:
const animated = document.querySelector('.animated');
animated.addEventListener('animationend', () => {
console.log('Animation ended');
});
The same, but using the onanimationend
event handler property:
const animated = document.querySelector('.animated');
animated.onanimationend = () => {
console.log('Animation ended');
};
