初识
React
React
是一款用于创建用户界面的流行库。它是
Facebook
为了辅助数据驱动的大型网
站解决某些问题而研发的。
2013
年
React
刚发布时，该项目受到了外界的一些质疑，
因为
React
的技术规范非常独特。

核心团队编写了名为“

”的文章建议读者

）
5
分钟”。他们鼓励人们摒弃先入为主的观念，先了解一下

弄得眼花缭乱，即一个能够解决所有和
DOM
相关问题的脚本库；该库可以大幅度减
轻我们的工作量，并且还不会让我们陷入沮丧。
然后问题接踵而至：如何转换
JSX
格式？如何载入数据？在哪里存放
CSS
文件？什么
是声明式编程？每种问题又会引出更多问题，比如用户如何将该库集成到日常的工作
中。每种规范又引入新术语、新技术和更多问题。
