Hahahaha anyone else catch the 'Meow' at 10:04?...right before he creates the useCat function.

[@davidurbina6555]

totally caught that. Re winded just to make sure haha

[@MrDots99]

Jumpin' around all nimbly-bimbly from function to function

[@user-ot1dv6ri4f]

came down here to comment about it haha

same I checked the comments if anyone else caught it too 😆😆😆

I liked the video when he says "Stack overflow". Perfection! 🤯

[@Ozzymand]

This account feels so satirical yet so educational. I fricking love you fireship, you're amazing

[@akhileshnarayan8547]

I love to watch your videos, especially the humorous parts! Loved the 'meow' @ 10:04 !

[@stephblank8204]

I have watched hours and hours of videos. I wish EVERY programming video explanation included what you said "You can think of ____ like _______" Thank you for knowing how to teach.

[@russelldriver6394]

You have done a fantastic job on these videos, really well done! The editing and comical quirks really keep the interest. Glad I stumbled across them.

[@dhruvilupadhyay1]

You are legend. Just from this one video, I basically leaned what I have been learning in JS from 3 months. Plus, you also state the mistakes you made, so learner like me can avoid it. Keep up the good work buddy

[@troythompson2]

Simplest recursion demo I've seen. Nice!

[@LawrenceTheGreat]

I think you nailed the style. These videos are a really great combination of clarity, humor, and substance.

[@RedEyedJedi]

Only found this channel today. Informative, funny and well-paced. So glad I found it. Subbed and binge-watching.

[@mmmike3426]

This is the best JS video I have ever watched. What a great job! Love it!!!

[@raymondmichael4987]

Laughing 🤣🤣 while watching especially "when dog gets a beer" Not always to watch and laugh this type of content, keep it up bro. Greetings from Tanzania 🇹🇿

[@Fireship]

Thank you! I like to have fun when I code :)

The "meow" (while saying now) really got me xD. 10:04

[@matheusazevedooliveira8222]

That's the quality content I'm subbed for... Thanks!

[@evolopterus]

Love your videos! Fast paced, information dense, beautifully presented. One thing I want even more of... dedicate a little extra time presenting best/recommended practices, because often there's many ways to do a similar thing in JS. (In this particular video, you do express an opinion on best practices, on other videos not so much. ) Thank you!

[@davesomeone4059]

I've watched a lot of tutorials. I still don't get it but at least this one got me to get it a little bit more.

[@juliohintze595]

This flexibility in functions definitely are one of the most beautiful things in JS

[@harrisjm62]

Thank you so much Fireship, you have been a lifesaver! This was the one thing that wasn't clicking for me since starting JS on freeCodeCamp.

[@mohyeachraf8489]

LOVED the refenrece of The Bachlorette in the case of pure functions and global variables, keep up the good work such value to the youtube Javascript community, Thank you.

[@Fireship]

Mohyeddine... Will you accept this rose 🌹

[@divinedela9125]

"The best way to understand these concepts is to get a lot of practice." Another Great video . Thanks Jeff

[@janhiness]

Thank you, I’ve been struggling understanding functions but you helped and even got a few laughs 🤣 which is rare when learning js.

[@vladimirjean]

Like always, awesome videos, looking forward to watching the next one, keep it up!

[@liamsmith-yp3xh]

Far to fast for a complete beginner but for an intermediate level there’s a lot of valuable things here, gained a deeper understanding, also you can just return something even bigger than a single array after an arrow function by wrapping in brackets or if you need to return an object. Didn’t realise a function returns always even if it’s undefined but makes sense with return function ending

[@aBradApple]

Not sure if I should be watching this after a week into learning to program, but it's nice to help shape my mindset for the coming months.

[@fantasymels]

This is crazy. In the first 5 mins, so many concepts clicked for me.

[@flyte9844]

this can't only have 83k , that series is so awesome anyone who do js stuff need to watch it either to learn or just for entertainment.

[@LynnK2000]

Definitely the most engaging programming course I've found online, I always look forward to your uploads. Keep up the good work 🙂

HOW EVERYTHING GOING BY FAR

[@abrobaTVOficial]

Your work is awesome! Just wanted to thank you for these videos.

[@thanhlengoc3805]

Thanks for giving tips on lots of basic stuff that I have ignored the whole time.

[@StickWithFiddle]

Great video! Only wish he spoke a little slower to let the concepts sink in before moving onto the next function type. Also an example of a real life situation you might use each of the different functions would add value for beginners.

[@SSGVB]

I felt the same way until I found out about playback speed in the settings

[@Dzigi89]

Awesome video, can't be simpler than this, thank you sir!

[@alvarezsoto]

Superb guide! It was nice learning how react hooks use closures.

[@macokaba1964]

Truely amazing that just when I learned all this in university you make a video about it

For anyone who wants to learn about functions in a deeper way, I highly recommend the podcast LamdaCast. It really took my programming understanding to the next level. 👍🏻

5:40 Please release the video soon, I want to learn more about Object-Oriented JavaScript.

Thanks for the helpful video! Is there an extension that outputs your console logs right there on your code or are you just adding it as comments?

It's an extension called 'quokka'

Superbbbbbbb 👍

all was good but the recursion part was a pain in the AAAAA.. i hope there will be a video on the event loop and how to write non-blocking code XD

[@johnmikelregida7142]

Fan of your videos since I found out about Angular Firebase! ❤️ Just a quick question, what’s the plugin that you use that gives the realtime comments (like on 8:22)? Or did you edit the video with it?

[@gonzalolopezbascur8078]

Hi, i think that he is using this plugin: quokkajs.com/

[@alsaamit]

Ohh Man .. Which Theme do you use in Vs code ? .. i like everything about you your content and your Theme XD

[@dibbyo456]

Now I understood why Jeff Atwood named "StackOverflow "

[@pberhe2]

Thank you for this video, Great content! I think I just have to slow this video down to playback speed .5 to really get how to do this because some info clicked pretty fast. Kind of starting to question my ability to retain information knowing you made this for kids though. I think im joking 🤯

[@flowerjamcc2853]

Now that its 2023, what do uu think is the cool and important JavaScript video that is missing from the internet ? Make it please 😃🤩

[@anderskok9919]

What extensions do you use, more specifically the extension that comments your code real time?

Do you know how to show the debugg information after the code like in the video?Thank you.
