var Module = (function () {
    let modules = []

    function define (mod, dependencies, func) {
        let depens = {}
        dependencies.forEach((depend, key) => {
            depens[depend] = modules[depend] 
        })

        modules[mod] = func.call(func, depens)
    }

    function require (mod) {
        return modules[mod]
    }

    return {
        define,
        require
    }
})()

// test
Module.define('foo', [], function () {
    function sayHi () {
        console.log('say hi')
    }

    return {
        sayHi
    }
})

Module.define('bar', ['foo'], function (depends) {
    function sayHello () {
        depends.foo.sayHi()
        console.log('say hello')
    }

    return {
        sayHello
    }
})

const bar = Module.require('bar')
bar.sayHello()

有点事做，晚上再补充。
