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 iterations property of AnimationEffectTimingReadOnly represents the number of times the animation should repeat. It defaults to 1, and can also take a value of Infinity to make it loop infinitely.
Note: In AnimationEffectTiming, a mutable subclass of AnimationEffectTimingReadOnly used withKeyframeEffects, the property acts as both a getter and a setter.
// Getting the number of iterations var animationLoops = animation.effect.timing.iterations; // Setting the number of iterations animation.effect.timing.iterations = 2.3;
A whole number or decimal greater than or equal to 0, or Infinity. Defaults to 0.
In the Red Queen's Race example, we can inspect the timing property on the redQueen_alice animation to discover how many loops Alice and the Red Queen's animation has:
// Infinity return redQueen_alice.effect.timing.iterations;
