NodeJS ReferenceError Module

I just started to learn NodeJS and ran into a problem while learning modules.

I have 2 files place in the same directory, the first is app.js and the second is hello.js. In the app.js I wrote : 

const hello = require('./hello');
console.log(me);

In the second file, the hello.js file, I created an object and then exported it using module.exports : 

let me = {
    name : 'Bao Chan',
    age : 20,
    job : 'Developer',
    hobbies : ['Listen music', 'Play Videogames']
}

module.exports = me;

Then I saved 2 files and typed node app.js in the cmd but an error appeared : 

ReferenceError: me is not defined
    at Object.<anonymous> (E:\Web Dev Assets\Projects\nodejs-tut\app.js:2:13)
    at Module._compile (internal/modules/cjs/loader.js:1151:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1171:10)
    at Module.load (internal/modules/cjs/loader.js:1000:32)
    at Function.Module._load (internal/modules/cjs/loader.js:899:14)
    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:71:12)
    at internal/main/run_main_module.js:17:47

I've been stucking here for like an hour and still haven't figured it out, I don't know if I've missed installing anything or anything's wrong with my code, please help me, thank you guys so much.

Thank you guys so much, I've found the solution.

Try this :

hello.js

let me = {
    name : 'Bao Chan',
    age : 20,
    job : 'Developer',
    hobbies : ['Listen music', 'Play Videogames']
}

module.exports = {
    me: me
};

app.js

const hello = require('./hello');
console.log(hello.me);

You're requiring the hello file in a variable called hello not me (even though me is what you actually called the object in the hello.js file. Try console.log(hello)

You need to call me with the const which you have used for importing your file which is hello here

Try console.log(hello,"---")
