关于react.js:Redux-compose

读的比拟好的一篇文章：

https://www.jianshu.com/p/c9d…

export default function compose(...funcs) {if (funcs.length === 0) {return arg => arg}

  if (funcs.length === 1) {return funcs[0]
  }

  return funcs.reduce((a, b) => (...args) => a(b(...args)))
}

compose(f1, f2, f3, f4)(args)

执行程序是：f1(f2(f3(f4(args))))
