You might be tempted to use an item’s index in the array as its key. In fact, that’s what React will use if you don’t specify a key at all. But the order in which you render items will change over time if an item is inserted, deleted, or if the array gets reordered. Index as a key often leads to subtle and confusing bugs.

最好要用唯一 key,不要用数组的索引，如果要实现列表增删改查，排序的功能，用数组索引，会有 bug

• react-from-milk

• swr 请求库
