Wow I'm early as heck! It's dan the man! #RecursiveTrain

to understand recursion, you must first understand recursion

When the Sierpinski triangle just suddenly showed I burst out laughing :D

[jakieboiZ]

Sierpinski Triangle straight outta nowhere!

I can't believe that i actually understand all this video, is been a huge journey for me to actually learn java-script and I finally feel that i can understand it. i'm doing so much thing by me own thanks Daniel for this great channel with so much information!

Finally found an explanation on recursive functions that actually makes sense! Love that you thoroughly explained how your code worked, how you broke it down on the whiteboard, and how you used the circles as a visual example to illustrate what happened every time the recursion happened

The way he said '' I' m using a mac''. I don't know how to stop loving him.

I don't know why but I absolutely love recursive functions. Just mind melting thinking about how a function calls itself. For me it's like thinking about infinity.

I love you, you are an amazing teacher, I'm a teacher as well, and maybe one day I'll be a 10th as good as you. Love your videos/humor/teaching style. Thank you for sharing your knowledge with us!

I’ve been programming as a hobby for so many years and this helped close some gaps that I had in my recursion thinking. How you mentioned it’s a loop, which I already know but not I just think of it as when the recursive function comes in it just redoes the function from the beginning like in a for loop. Of course need exit conditions too

You should make a new series-something like Coding shorts which introduce an idea like recursion or 10print and let us the community build on the idea you provide.

#RecursiveRainbow would have been perfect.

but, you know...

[lizardkeeper]

I am so glad I found this video. I had a programming teach last year call recursion magic and told the class not to think about it. fractals I can wrap my head around magic I can't. I finally understand recursion, thank you!

[Lyrik-Klinge]

Your channel is so motivation!
As an adult you are playing with the code blocks like a child with his toy blocks to build great projects ... Go on!

[mmbower]

Nothing but good spirits and great learning on this channel

Is it possible to add z axis to the fractal?🤔
It would be amazing to visualize it in 3D😍

I remember when coding challenges were like "I'm going to do that and try in 10 minutes".
Now there isn't even a timer anymore :/

[jank-official]

I love your videos! You are always so animated and lively. Very inspiring! One question - you promote a lot of 'Coding Rainbow' and other things rainbow related. Do you identify as part of the community as well?

No recursion, less lines :)
Btw, nice video ;)

var sw = 300; //start width
var mw = 2; //minimal width

for(i = 0; (sw / Math.pow(2, i)) > mw; i++)
for(j = 0; j < Math.pow(2, i); j++)
ellipse((sw / Math.pow(2, i))*(1+2*j), 300, sw / Math.pow(2, i));
