React怎么用的两个例子我都有疑问：
1、将组件state中的数据转为immutabledata有啥好处，我们现在不转也运行的很好，什么场景下才需要用到？
2、第二个，即使info没有使用immutable，只改变了age，pureComponent也是比较的出来的啊,child不会重新渲染，因为此时info传下去的值是一样的

@hhhuangqiong 关于immutable的优势和实现原理 可以看下这个 https://www.youtube.com/watch?v=Wo0qiGPSV-s&t=4s 、通俗来讲就是在修改复杂数据类型的时候会返回一个新的对象而不是直接在原本的对象上修改 避免造成数据混乱
这里有一个用immutable实现的五子棋 https://github.com/Jemair/fiveGo immutable的优势在todo 和 redo 里体现的很充分
