node.js - nodejs express module.exports问题

Question

我知道模块化可以这么写:

module.exports = {
    a: function(){
        console.log("这是a");
    },
    b: function(){
        console.log("这是b");
    }
}

请问可以这么写吗？

module.exports = function(){
    console.log("这是模块");
}

....Can't you just try it yourself? There is an object everywhere above and a function everywhere below. . . Any questions? practice. . Out of true knowledge. . .
