branch 介绍

branch方法接收三个函数参数，第一个函数返回一个布尔值如果为true则调用branch第二个函数，如果为false则调用branch第三个函数。第二个和第三个为高阶函数，在函数里面可以为组件增强功能。

branch(
  test: (props: Object) => boolean,
  left: HigherOrderComponent,
  right: ?HigherOrderComponent
): HigherOrderComponent

const { compose, branch, withProps } = Recompose;

    withProps({ title: '我被显示了' }),
    withProps({ title: '你看不到我' }),
  ),
)(({ title }) => (
