请教一下楼主，
src/components/articles/articles.js文件第125行，如下图所示：
每次下拉触发ajax请求，取回了一定数量的的数据，每取回一次都要和已经取回的数据进行一次合并操作，当一直往下拉的时候，数据会越来越多，数组越来越大，会不会性能很差呢？
性能会变差的，小数据能这么做，当然有很大数据时最好就不要了，用扩展运算符 ... 会好点。

这里的 setState 用 prevState 好点吧

我没用官方 demo 的写法，这么写我感觉不错。code标签就不用你自己写样式了

查了一下，是 prevState 好；marked 的用法好多的，好用就好。
