My React Native component has a prop this.props.a that gets updated every 60s elsewhere in the app. Within this component, I have a <View> with an onLayout() function. This onLayout gets called every 60s when the props are updated. Is there a way to get it to be called only the first time the component is rendered, and not on subsequent re-renders?

Yes! <View onLayout={()=> onLayout()}/> This part ()=>will prevent the onLayout function form being called on render.

Hope this helps! /W
