Your method of teaching is kind of genius. You gave us a real world case and broke it down in the same way that a computer would understand it. Simultaneously teaching it in a more intuitive way so that a person can as well. That there is something that 99% of educators fail to do, kudos to you, dude.
The bubble-up is misleading because the computer did not actually do it. the computer simply broke down the function until it reached factorial(1) where it returned 1. It popped off. not the bubble up. factorial(5)stack will be at rock bottom.

@@Lion-st5g3s378 no if you look at it, you stacked the execution contexts until the function returns 1 visually: stack 4: factorial (1) - stack 3: factorial (2) stack 2: factorial(3) stack 1: factorial (4) ==> at the global execution context last in first out. again it popped off not bubbled up. don't ask me but Brendan eich lol
I have been trying to read the recursion description on free code camp, but I couldn't grasp the concept. Your explanation helped so much. Thank you and please keep making these videos.
Best simple and great example. Must watch video. I already know what is recursion but i watched this because this topic is not explained by anyone with clarity. But this person did.
Thank you, buddy, I have solved my problem . I was seeing lots of videos about recursion, but I did not understand actual things about recursion. When I am seeing your video about recursion, that's time I finally clear my doubt about recursion. Thank you, buddy.
Dude, you're literally the only one who made it look easy. I didn't get recursion before but thanks to you now it's clear like a lake in Switzerland. Thank you very much!
This was PERFECT!! I got a "RangeError: Maximum call stack size exceeded" and from there found out it was because I was trying to do recursion without a base case. I had heard of recursion before, and heard about recursion needing a base case in order to have an exit - but I'd never been formally taught recursion so didn't know precisely what it was or how to implement it. After watching your video, I saw that the function in my head I was trying to achieve was recursive - and also understood exactly what I need to do to write my function correctly. Super excited! thank you! :)
I was about to cry trying to understand merge sort until I found this video. Thanks for the explanation; it's probably one of the best explanations about recursive functions out there.
This is about as straightforward as it gets. I've been curious about the consequences of breaking things down into smaller parts, and you've just given me a clear explanation. Your tutorial is great, right to the point.
when as a beginner I listen these type of Js terms, I get demotivated and consider programming is not my thing but teacher like you are the only hope. Thank you @Devsage for your effort.
I was reading on the recursion concept in Eloquent Javascript then I watched this, and with the help of both I would say now I understand 95% of what recursion is. Thanks.
Thanks for explaining this so clearly. I've been doing Hackerrank 30 Days of Code for JS and it's had me in tears, but the way you explained this concept makes sense to my brain. I'll be back :)
Holy shit this is the best explanation. If everyone teaching programming explained things like this then maybe many of us who can't wrap our heads around complex concepts after hearing them only once wouldn't feel so discouraged from trying to learn how to code from the get-go.
Hands down, best explanation of recursion on TH-cam... You definitely accomplished your goal of explaining a rather unintuitive concept in a very thorough yet approachable manner, kudos!
I have been watching other TH-cam video for Recursion explanation but confused more after one and another Until I found this video - this is video that has key to my brain and made me understand how recursion work! thank you
Find the chocolate! Unload the dolls! Bubble up! Finally a video that actually explains recursion to a level of understanding! I have watched and read so many other things to no avail and THIS video using physical things and a journey I can imagine helped me get that ah ha! moment. THANK YOU! Subscribed!
Best explaination I've seen. Afters months of feeling guilty for being stupid, I can finally share the blame with my teachers. THANK YOU SO MUCH FOR IT!
So glad I found this! I was doing a lesson on freeCodeCamp and I could understand what was happening at a surface level, but I knew I'd never be able to actually apply this technique without understanding what the computer was actually DOING. This is dead simple once it's explained.
bro love you (no homo), the factorial explanation made it so damn cleaer. Been suffering a lot trying to understand this stuff. you are the only one I found who explains step by step.
You genius. Thank's for simplifying this for my simple mind. I was reading up on this and couldn't understand where they got the 'n - 1' from. This has really helped.
I quite literally can't give this video enough likes. I've been rattling my head for a week on this part of free code camp and even bought a book to learn it. This video was like a light bulb going off. Thank you!
Woah dude. You are the best. I like how you didn't jump into the code straight up and actually tried to explain it with real world example which made everything so clear.
I wish all my programming instruction was this clear. It always seems like concepts that wouldn't be clear to a beginner--like the bubbling up-- are left out. This was extremely helpful. Thank you!
I don't think you understand how much greatness you were able to contribute to humanity through this one video. You have such a talent for communicating concepts so clearly. THANK YOUUU!!!!
Dude was breathing so hard that he depleted the oxygen in my room to dangerously low levels. Currently writing this from the emergency room. Also amazing recursion explanation! Genuinely couldn't wrap my head around it before this video. Thanks.
This is truly the Best Recursion Video, no cap.... Even Chatgpt couldn't explain it this well to me... Gonna save the video.... Nice one brother... Thanks
I must say I had really hard time to wrap my mind around recursion in practice and all explanations were just to abstract (sometimes I wonder if it's on purpose to show off the superiority of the one doing the explaining). I was looking for an explanation just like this - simple, intuitive and most important of all showing what actually happens when the code is executed. Thank you so much!
I've seen a lot of explanation videos about recursive functions and I did't understand it but now I finally get it. Your way of explanation is very clear and this Matryoshka dolls example totally helped. Thanks a lot!
Thank you!!! My goodness, I knew recursion had to be simple, but couldn't seem to wrap my mind around it. Now any time I use it I'll be thinking of the russian stacking dolls!

can you go over the freecodecamp recursion lesson (which is lesson 103 in basic javascript)
@@slewbp this explanation has helped me understand those fcc recursion lessons.
Thank you @DevSage
You're not joking, that really was the best recursion explanation. Just went from clueless to fully understanding it and it was really satisfying.
legit.

This should be shown to everyone who is trying to understand recursion. So simple and clear. Thank you!
You're welcome
Recursion looks so scary to learn, then it gets explained like this and you realize its actually pretty simple, thankyou!
No problem
good explanation.
THE BUBBLE UP moment is the main point of this recursion.
the bubble up was definitely my "ah-hah" moment!
Same here!!!!🙌🙌🙌

@@passableespresso5068 Hi! I think the bubble-up it's okay. The computer is doing something like this:
factorial(4) -> else n = 4
n*factorial(n-1)_i -> else n = 3
n*factorial(n-1)_ii -> else n = 2
n*factorial(n-1)_iii -> return n = 1
n*factorial(n-1)_ii -> n = 2 * n*factorial(n-1)_iii = 1 = 2*1 = 2
n*factorial(n-1)_i -> n = 3 * n*factorial(n-1)_ii = 3 = 3*2 = 6
n*factorial(4) -> n = 4 * n*factorial(n-1)_i = 6 = 4*6 = 24
Hope it helps :)
@@Lion-st5g3s378 no if you look at it, you stacked the execution contexts until the function returns 1
visually:
stack 4: factorial (1) -
stack 3: factorial (2)
stack 2: factorial(3)
stack 1: factorial (4) ==> at the global execution context
last in first out. again it popped off not bubbled up. don't ask me but Brendan eich lol
The bubble up part is exactly what I need to close the gap on understand recursion fully. Thanks!
No problem 💯
I have been trying to read the recursion description on free code camp, but I couldn't grasp the concept. Your explanation helped so much. Thank you and please keep making these videos.
No problem
FreeCodeCamp didn't make this any easier.
I came from FreeCodeCamp as well, damn. This video made it so much easier to understand than the one they link to.
Same here 😂
Same with me. I've been losing it ever since I started Loops
Nice, clear explanation. The part around the 8 minute mark where you type out each recursive call and explain how they bubble up was great. Thanks!
What made it click for me was the fact that the same function is calling itself with slightly different arguments.
Great stuff!
Wow. Every explanation I have heard never made sense until this one. That “bubbling up” really made it clear for me. Thank you!
Glad it helped!

The way you laid out how the recursion calls play out once the base case is met, from 8:45 onward, is dope.
Thank you.
This is the best explanation of this concept I've found so far
This is about as straightforward as it gets. I've been curious about the consequences of breaking things down into smaller parts, and you've just given me a clear explanation. Your tutorial is great, right to the point.
The Word "Bubbles Up" was everything I needed to grasp the concept. Thanks
I only understood it from you, after I scanned all the TH-cam on Recursion. Your title is fulfilling it’s promise.
Aaaaah. What a great analogy! The matroshka really illustrates everything with recursion!
You gave me the "ah-hah" moment, thank you!
Glad I could help!
Same vibe here.
Dude you literally taught me something new, I couldn’t grasp my head around recursions and you literally taught me something new.

Thank you a lot. Previously I watched many videos, but can not understand what was happening in a recursive function. Now finally got it.
No problem
Actually a really simple way of understanding it. Had to rewatch a couple times around the 07:30 mark but made sense of it in the end. Thanks!
showing how it lays out and then calculates in backwards from the base is all it took. made it click! Thanks!

you are awesome, I've been scratching my head with this concept for an hour.. and why u cleared it in 10 minutes.. thanks man
So clear and simple, will definitely be watching more videos!
Saved it and will show it anyother who could be confused about recursion , very good explanation
This really was the *BEST* recursion explanation. I love the analogy with the russian dolls. Thank you so much!
I normally don't take the time to comment on many videos, but your explanation is incredible! Thank you
Appreciate it, Flavio
Everyone must understand from her I took 3 days from other sources but could not understand but with just one video from her I understood all
Thank you! 4 years later this vid helped me so much!
The best est javascript recursion explanation on TH-cam indeed. Thanks man

Appreciate it! 😁
this is really the best explanation about recusivity ive have ever seen, im sharing now with my friends
Thanks Gabriel 😅
Just cracked the Eloquent JavaScript chapter 3 exercise thanks to this! Respect mah brotha!
Glad it helped
Step by Step walk through. Great Teaching
Thank u, I’ve been looking for a video that could explain me it. No one on TH-cam explained it better than u did.

This is the exact video I needed. Much more of a comprehensive explanation than 99% of the other videos out there.
fantastic! Very simply explained. This not only solved my problem of understanding recursion, but many others!
to be honest this is the best explaination i have seen on youtube.

3 years later and I came for the same reason: I could not get this based on freeCodeCamp's explanation. Now I got it. Thank you.
Awesome! Had troubles understanding Javascript Recursion until i saw this video. Great job and thanks.
the best explanation of recursions, thank you
