What is a monad? (Design Pattern) 

Hiya! It turns out that what is described in this video is the Functor and not the Monad. The difference between these two is quite minor so I'll leave it here. A monad is just a functor which has some extra property within the bind method. Functions being passed in bind calls must have as their return types an instance of the monad being used. The bind method of a monad would then need to "unwrap" that value.

A monad is just a monoid in the category of endofunctors. I don't know what people don't get about that.

I'm a big fan of the "fireship style" of videos and it's great to see more people creating high quality content like this

I already know what a monad is: it's that thing that my annoying friend who's just learned Haskell won't stop talking about

This 2 minute video is a better explanation of monads than some hour long lecture I've watched. Really good stuff!

You may be very small now, but with this quality of content you will definitely be big one day!

Fireship's influence shows. You're also just as talented at explaining complex things in a short time.

I commend you for having so clearly and accessibly explained a notoriously difficult topic. I finally feel like I actually understand what these are now. Thanks!

These videos are well made, keep making them!

This has to be the best explanation of Monads I have found out of all the many, many, many videos I have watched, and definitely the most productive 2 minutes and 30 second - highly recommended. I suspect one of the major difficulties with explaining the concept are the different mindsets of the audience from the instructor. The vast majority of instructors will be from a declarative/Functional Programming background where solutions are defined in terms of what needs to be done. The audience will largely comprise developers from an imperative OOP/Procedural background where solutions are formed by defining the steps required to resolve the problem. Having an explanation in terms of how the monad resolves a problem by absorbing some of the steps is really easy to understand. The last 60 seconds of this video really hits that message home, but I would not go as far as to suggest watching the video in reverse.

What can I do to make my future videos better? Any feedback (even negative) is much appreciated!

Great video±! You have enlightened my vision on computer science by finally explaining to me what a monad is dude.

That’s probably the best concise explanation of monad I’ve read so far!

To the point, concise and clear explanation. Just what a developer needs.

The best explanation I've seen so far, yet by far the shortest too. Great work!

This is the most comprehensible explanation of monads I've come across. Thanks.

This is the most clear and intuitive explanation of monad I ever had. Thanks

Most clear and concise explanation of monads that I've seen - amazing stuff

There have been many attempts to explain monads and many have failed but your example makes it extremely clear, thank you

The best Monad explanation I've seen so far.

Insane quality of content for a channel so small. You've earned my subscription

Being a functor or a monad doesn't matter you've done a brilliant video in a beautiful way that would hopefully inspire newer developers to be better, respect to you

This is so incredible. So simple understandable and clear. Well done!!

Very short and sweet explanation! I like how you explained concisely the reason to use monads and how they basically work

God-tier explanation, extremely concise and easy to understand. Thank you!

I am glad that I found this channel, I love to learn something new like algorithms and complex information rather than seeing basic stuff and useless tutorials,. Keep it up man

your content is fresh and I don't see this type of content anywhere else, subbed!

Wow, that was a very clear explanation ! Now I know how useful monads are. Unfortunately, I already forgot what they are.

I love you. I was referred to a 12 mins video about monads, I watched all of it and I swear I had no idea what it was talking about. I got the clear idea of what monads are in 2 short minutes.

After years of visiting this topic, I finally get it. Thanks!

Hands down the best explanation of Monads I have seen on youtube.

Very good video; all killer, no filler.

Short and sweet. Very well explained. Thank you!

You are an excellent instructor. I will stick with you.

This is best explanation ever I got about Monad or Functor for that matter!

This is the best explanation I have ever heard thank you

You're a gem, my friend. Keep up the great work!

Very cool, much impressed! Glad to have found your channel.

I still don't understand monads 100%, But this video is where I can say I got the closest to understand them. And the most surprising thing is the video length! I have watched, before this, a lot of other videos about monads, and some of them were really long and thorough, but I consider this one is the best so far. I can't be sure whether it's the example you gave or the fact that I'm watching this after watching many similar videos, but this is defiantly QUALITY CONTENT, short, concise, holistic and well-narrate. Thankyou very much

I absolutely love that your video is very readable. A lot of content creators make content that's unwatchable unless you're a freakin' eagle.

Whoa, sifted through a lot of Haskell literature and was none the wiser. Thanks for the succinct explanation.

This is awesome! Thank you for this easy-to-understand video

So much info in ~3 minutes, great 🔥

So excited to see what comes next with ur channel, keep up the great work :)

Best explaining Monad ever.

Actually the most understandable explanation and nearly the fastest, didn't expect that from such small channel, keep it up)

Finallyyy i understood it, computerphile video was complicated for me, your small example was really easy to understand

This is the first explanation I've heard that makes sense.

Thank you. I still don't understand monads, but this is the very first video which gives me hope that I might understand monads one day.

Devastating synthesis, straight to the point. Subscribed.

This is awesome! Thank you for the explanation!

That video is awesome, congrats for the great content!

Now yes, a decent quality video. Keep up the good work man!

Finally understood why I would want a monad

Wow the quality of this content is just unbelievable, keep it going

first channel that i subscried after only wathing one video . Amazing content.

After watching this video again after months and others of countless explanations + category theory, I think I'm finally beginning to get it

Great video. Easy to follow with beautiful graphics. Thanks. :)

Easy, to the point explanation, subbed, looking forward to new videos!

Such a good explanation. Thanks!

Wow, such a short video but better than the 10 to 14 minute videos I've watched. Well done.

This is the best explanation ever

Holy crap, this is super useful and a way of thinking that I haven’t thought of before. Nice work!

Good Job. You're on the rise!

Such a simple and precise explanation... wow, 100% immediate sub, please keep up the nice work!

honestly pretty cool and well explained

Amazing content. Will share this with my NL audience. I'm sure you will blow up

In 2 minutes you explain concept that everyone else can't explain in 20 minutes or more!

Great explanation, thanks!

Wow, I have been developing for 7 years, and I did not know about this, very cool!

thanks, this was really helpful!

This is interesting first time hearing about monad, pretty interesting to try

I like it, direct to the concept

This is lovely. Looking forward to seeing more from you. Subbed!

incredible content this is what the people need

That's some quality content!

You earned yourself a follow!

strong, powerful, simple, great video

Great explanation.

Good!! thanks for this content!

Wow. Finally understood this concept. You have talent. Keep going.

Very clear example, keep up the good work 🙂

I love how monads are explained with such example that fights JS absurdity

This... Is pretty cool, thanks!

Subscribed at 12.7k! See you at a million in just a bit.

Excellent video!

That's amazing, thanks!

Nicely explained!

This video is more like a text book to teach how to make people subscribe in 2.5mins Informative, clear, interactive expression Instant subscribed

Pretty great explanation. Thanks. Would love the video to be longer with more examples.

this video is so good that im pissed. this concept is literally so simple and yet all the "explanations" existing online are like "hey buddy youre gonna need a computer philosophy degree for this" and then explain nothing. but like this + your clarifying comment make crystal clear sense. im so pissed. great work

A really great video! I hope your success as a RU-vidr comes soon.

Next big programming channel 💪

wow, this is so easy! subbed!

Excellent video bro.

Great video!!

Great technique!

Finally an actual explanation of a monad.

This is amazing

Not even 3 minutes, straight to the point and had me saying "oooohhhhh, no f*cking way it was this simple" at the end. 10/10 video
