真的是历经磨难，花了三四个小时，才写正确一个react component

第一次进入新的领域，令人兴奋，又令人备受折磨。

第一个接书上来的react组件，写起来也是一波三折。

不提class大小写，不提如何用低版本的prop-types作验证，不提在eslint里屏蔽一些问题("react/prefer-stateless-function": "off","import/no-named-as-default": 0,"import/no-named-as-default-member": 0,)，不提HtmlwebpackPlugin如何生成模板，更不提空格和tab，单引号和双引号，XXXX，，啥也不提，上个文件记录，知道我曾查过很多资料，解决过这些问题。
