One more thing we can do to further optimize our carousel is wrap our Slide element in React.memo.,That's it! I've added a pagination component and tweaked the styles a bit and here's how the end product looks like.,In the end we can move the style outside of the component definition and wrap the renderItem function in useCallback to avoid our FlatList re-rendering unnecessarily.

const {
   width: windowWidth,
   height: windowHeight
} = Dimensions.get("window");

const slideList = Array.from({
   length: 30
}).map((_, i) => {
   return {
      id: i,
      image: `https://picsum.photos/1440/2842?random=${i}`,
      title: `This is the title! ${i + 1}`,
      subtitle: `This is the subtitle ${i + 1}!`,
   };
});

At Auquan, we recently decided to redo our websites and optimize them for the mobile view. Our aim was to do some design changes for a better mobile experience and also clear out some tech debt along the way. We made a lot of structural changes in our code, adopted styled-components and eventually ended up building up a well defined react component library. This is important for us as we wanted to reuse many of these designs and components frequently in future.
