react redux compose代码

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)))
}

import { compose } 'redux'；

// function f
const f = (arg) => `函数f(${arg})` 

// function g
const g = (arg) => `函数g(${arg})`

// function h 最后一个函数可以接受多个参数
const h = (...arg) => `函数h(${arg.join('_')})`

console.log(compose(f,g,h)('a', 'b', 'c')) //函数f(函数g(函数h(a_b_c)))
