Using InteractionManager can be a good approach, but if the user experience cost is too high to delay work during an animation, then you might want to consider LayoutAnimation. -The Animated api currently calculates each keyframe on-demand on the JavaScript thread, while LayoutAnimation leverages Core Animation and is unaffected by JS thread and main thread frame drops. +The Animated API currently calculates each keyframe on-demand on the JavaScript thread unless you [set `useNativeDriver: true`](https://facebook.github.io/react-native/blog/2017/02/14/using-native-driver-for-animated.html#how-do-i-use-this-in-my-app), while LayoutAnimation leverages Core Animation and is unaffected by JS thread and main thread frame drops. One case where I have used this is for animating in a modal (sliding down from top and fading in a translucent overlay) while initializing and perhaps receiving responses for several network requests, rendering the contents of the modal, and updating the view where the modal was opened from.
