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

[@frankatwestern]

[@bolow]

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

The content on this channel is great, but your voice is why I keep watching/listening.

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

[@G3ntiLP]

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

[@LawrenceTheGreat]

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

[@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.

[@akhileshnarayan8547]

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

[@troythompson2]

Simplest recursion demo I've seen. Nice!

[@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!!!

[@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.

[@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

[@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

[@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.

[@matheusazevedooliveira8222]

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

[@janhiness]

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

[@juliohintze595]

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

[@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 🌹

[@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!

[@searchingForMinimalism]

The content quality is way too high ! thanks for the great piece of art.

[@divinedela9125]

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

[@fantasymels]

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

[@vladimirjean]

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

[@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

[@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 🇹🇿

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.

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

[@vector5g143]

HOW EVERYTHING GOING BY FAR

[@abrobaTVOficial]

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

[@alvarezsoto]

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

[@Dzigi89]

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

[@thanhlengoc3805]

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

[@feschber]

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

[@abhishekyakhmi]

Please , bro we need more of this course you are really good at covering important topic fast

[@anesukafesu7875]

This channel teaches me the best developer practices. And how to write better JS code.

[@beickerzambrano5908]

Great video, i've watched some ways to write JS code but you say new interesants things to me.

[@YashGupta-dr5re]

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

[@dawid_dahl]

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. 👍🏻

[@erdmax_]

Yes! The video we needed, but not one we deserve

Amazing video Jeff! Thanks for the awesome content

8:30 I had always knew that you should treat PL as some sort of fighting game combo movelist notation.

+1 for the 'meow' at 10:00

[@The-Average-Gamer]

Love your content!! Any ETA on the angular course?

[@hannanel100]

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?

[@fullstacklogan]

It's an extension called 'quokka'

[@mohithadiyal6083]

High quality production👍

[@AmeixaNerd]

Excellent content!

[@jugzster]

Douglas Crockford 😆 clearly explained concepts as usual, with funny pop culture references!

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

What extention is used to display output of console in vs code?

Look at that schoolhouse rock interlude. Haha Kudos for creative impact...

[@alexandervashchuk7795]

how do you get these live console logs ?

Jeff, this is amazing how you can you simply describe complex concepts! One of the best web dev channels! Than you

[@BradenJohnYoung]

Jolly good!

[@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/

[@MizikeDM]

5:16 if you only have one parameter you can also omit the parentheses.

[@user-vg7zv5us5r]

8:20 Does JS have a command list like in Tekken and the area, platform to practice combos, ahem, functions?

[@davesomeone4059]

Yes

[@superyngo]

this and self in function now refers to windows?right?

[@ZeeshanElia]

Superbbbbbbb 👍

[@wchorski]

To help me understand better. const [ meow, setName ] = useCat(); the "meow" function is just calling the first "useCat();" and "setName" is calling "newName"?

[@mridulbarman027]

Bro your videos are more than MIT ❣️

How do you use these icons in V.S. Code? they look so cool! (started programming a week ago😵‍💫😬)

How do you use emojis in vscode?

[@devi_buns]

How do you add emojis in your code ?

[@Luxcium]

11:03 I don’t understand what is maximum call stack size exceeded ... Should I reach to stack overflow to get an answer because to do that will be an impossible recursive task to achieve 😜

[@gladstonross12]

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

[@dibbyo456]

Now I understood why Jeff Atwood named "StackOverflow "
