 ### Returns
 
 `withRepeat` returns an [animation object](/docs/fundamentals/glossary#animation-object) which holds the current state of the animation. It can be either assigned directly to a [shared value](/docs/fundamentals/glossary#shared-value) or can be used as a value for a style object returned from [useAnimatedStyle](docs/core/useAnimatedStyle).
