35,526 PointsHow does this work?
So In the node.js basics Q/Ans. I found this -
Given the following code in greeting.js:
function sayGreeting() {
console.log("Hello World");
}
module.exports.say = sayGreeting;
How would you access the functionality from another file?
Now I figured out the answer. It's option A:
A ) const greeting = require("./greeting");
greeting.say();
B ) const greeting = require("./greeting");
greeting.sayGreeting();
Now, how come the 1st one works and the second one doesn't? I don't get it.

Treehouse TeacherHi there! The key lies in this line:
module.exports.say = sayGreeting;
It was exported as say. Now we could've picked any valid JavaScript variable here, but we picked one that made sense. When I first saw the require statement I thought it was pulling in the entire file that was being required, but I was wrong. I'm wondering if this is what you thought, too. It turns out that what is returned by the require are the modules that are exported. Here, the module being exported is named say.
Hope this helps!
