实现 compose 函数, 类似于 koa 的中间件洋葱模型

// 题目需求
let middleware = []
middleware.push((next) => {
    console.log(1)
    next()
    console.log(1.1)
})
middleware.push((next) => {
    console.log(2)
    next()
    console.log(2.1)
})
middleware.push((next) => {
    console.log(3)
    next()
    console.log(3.1)
})

let fn = compose(middleware)
fn()


/*
1
2
3
3.1
2.1
1.1
*/

//实现compose函数
function compose(middlewares) {

}
