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 iterationComposite property of a KeyframeEffectReadOnly or a KeyframeEffect resolves how the the animation's property value changes accumulate or override each other upon each of the animation's iterations.
Note: For KeyframeEffect, this property is both a getter and a setter. For KeyframeEffectReadOnly, it is read-only.
// getting var iterationCompositeEnumeration = keyframeEffect.iterationComposite; // setting keyframeEffect.iterationComposite = replace;
