I saw this article on performance issues, maybe the iOS version of JSC has the same problem? [https://dev.to/anotherjsguy/react-native-memory-profiling-jsc-vs-v8-vs-hermes-1c76](url)

iOS JSC not open JIT feature. Our app doesn't need to be on the Apple Store, so we don't need Apple to review, we want to open JIT.

collectionView 每次左右滑动, 浏览记录的offset都是从0开始, 如果要做到记录, 工作量又增加了. 还有, 用collectionView, 下拉刷新是个问题. 左右滑动的视图复用看起来简单, 做起来工作量很多.

ScrollView如果不是复用的话，十几二十个列表，内存占用一两百M，被杀死是必然的
