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.effect property of the Web Animations API gets and sets the target effect of an animation. The target effect may be either an effect object of a type based on AnimationEffectReadOnly, such as KeyframeEffect, or null.
var effect = Animation.effect; Animation.effect = AnimationEffectReadOnly
A AnimationEffectReadOnly object describing the target animation effect for the animation, or null to indicate no active effect.
