There is an easier way to do this in ES6. In stuff.js you can use Object Literal Shorthand:
module.exports = {counter, adder, pi} // if the property and value of an object is the same you can simply write the property name only (In ES6 only).
In app.js you can use Destructuring:
var {counter, adder, pi} = require('./stuff') // This makes it easier because you won't have to write stuff.Name every time you get anything from the module (Also in ES6 only).

I hope you never stop making tutorials. Ever. I mean seriously, after all is gone and we're in the middle of an apocalypse selling out our own grandma for a can of beans. I would still like to think you're out there in a cave somewhere with great wifi uploading more tutorials.

In ES6, there's a shorter way to initialize the module.exports object :

module.exports = {
counter,
adder,
pi
}

This works only when both the property and the value names are identical. So, instead of saying -> counter: counter in the object twice, we only say -> counter.

Highly recommend following along in your text editor at home. I previously watched all of these without coding and it felt like I forgot it as soon as I finished watching. When you do it yourself, it feels more imprinted in the brain.

These tutorials are excellent. I have watched so many tutorials but none has as clear explanations as yours. I am not going to skip ads on your videos as a thank you!

[johnyonardpauly]

You can also do things like this:


module.exports = {
counter(arr) {
return `There are ${arr.length} elements in this array!`
},
adder(a, b) {
return `The sum of the two numbers is ${a + b}.`
},
pi: 3.145
}


Thank you for a good tutorial series :)

Man you are just too good. You have a knack for simplifying hard concepts. thank you so much man.

[auchucknorris]

the size chuck of each tutorial is very well organised, thanks for the great series, super easy to follow, barely even have to pause

[athulmurali]

I was quite perplexed after the previous video. But this one cleared all my doubts. Thanks a ton

[koushikut]

Thank you for great tutorials. I keep coming back for reference.

Just want to add another way of exporting:

// **** //
var stuff = { };

stuff.counter = function ( arr ){
// inside logic
}

stuff.adder = function ( a, b ) {
// adder logic
}

stuff.pi = 3.14;

module.exports = stuff;

Hey man you are honestly a great teacher, came here for NodeJS but realized this guy might be able to teach me JS better than others. So yeah I am gonna stick around a little longer. I already know where I am headed to after finishing this series.
Thanks Mate

[JoshBowman]

this series has made so many things clearer that I had no idea about because they were so confusing to me previously. Top work!

[yohrocks]

the way you explain things is just amazing. thanks for sharing your knowledge.

[mshimanshu]

I like the object way of exporting things ...AWESOME, BEST TUTORIAL ON THE PLANET

[boring-username]

Your videos explicitly answer questions I have in previous videos and it blows my mind

[suemendez]

You break things down in way that anyone can learn, Thanks, and keep up the good work.

[morezco]

Thank you. JS Modules always got me confused because of the way I was used to thinking about JS and you made it so so simple.

[kunalpuri]

Doing great job Ninja.. Best tutorial so far on youtube for beginners.

[wounky]

Thank you for the tutorial, it is a true jewel comparing to others. Not only you hit right into the topic with every detail but you could also be a great radio speaker! I could listen to you for hours ;)

[jeteloriaga]

you are a verygood teacher! brief yet complete, discussing just what needs to be discussed. thank you!
