Are you a GOD or what? Yesterday I watched your whole Chrome Extension Series where you gave a huge amount of knowledge in just 11 videos, so it took me 1 day to digest that...and today morning I watched your videos of ( 1.1 p5.js) of 2015 which blew my mind and today itself you uploaded 2.1 of p5.js ....you are totally in my head !!! I know Your CONTENT IS FULL Of KNOWLEDGE. ANd the sound of the ring is not going out of my head.

Totally had a blast. Your lectures are small, fun and the best.

I really love your videos and your a great inspiration for me to start p5, and I never got bored seeing your video, pls don't ever stop doing this videos

[Roknok]

I am going to watch this even though I have seen the old version, just cant miss your videos. Especially when I get three consecutive videos as a treat!

It's really great to hang out with your videos and code along Dan. I'm not completely new to programming, but learning along with you is really refreshing and I'm excited to see where p5.js leads. I've just found they have a well maintained npm package to!

[adityakr.]

You made the coding very simple thing. You are great.

[davidmiranda]

I’m loving your way to explain you’re very funny and entertaining

From teaching/learning standpoint of view, p5 makes animation so easy. I know that many young parents have difficulty when choosing a programming language for their kids to start, python or java or c++ or something else? Here you are: p5.

My favorite class up to now, thanks a lot!

He kind of looks like Serj from System Of A Down, I love it :3

[osmermontilla]

this is fascinating videos. I am learning a lot, for my work as mathematician!! Thank you!!!

I can't believe that when I saw your hair turn white, my eyes were wet. I like you very much! I'm currently learning the icm class in ITP. I was scared of coding when I was in first day of class, but watching your video after class made me very relaxed, and I have a desire to continue learning. You are really humorous and energetic. I hope you will always be so happy and never grow old!!!

1:56 That's exactly what we're about to do with my old computer 😂
(Got a Mac Mini btw, my old Windows computer was making a stupid noise and we couldn't stop it, and it was also from 2015 so it made sense)
(EDIT: Literally a few minutes after I wrote this comment, our Apple keyboard arrived 🤣)

Feedback: the part when you beautifully explain the flow of p5.js is the most important one. Therefore, imo, the video should be called "p5.js flow and variables" or do two separate videos. Personally, the 1st option is the simplest and best. Love you and you're one of my fav teachers of all the infinite parallel universes of eternity.

[HectaSpyrit]

I will never understand the mechanisms impenetrable to the mind by which you number your videos :'(

[trysmarter]

Thank you for this big, important video!!!!

[leyshonrr]

Hey Dan, I'm working through your intro series (very much enjoying it, thank you for investing all this time and energy). Just to let you know, when I followed the end of video in-screen link that appears at the end of 1.6, it took me to an old version of 2.1 (sirens in background give a great startup feel). I was surprised to come back to the playlist pane in the top right of the YouTube interface to find you have also reworked module 2.

[enigmaticpuzzle]

These videos are very helpful, thank you so much
