JavaScript Promises -- Tutorial for Beginners

[@ColorCode-io]

🎉👨🏻‍💻 JavaScript Promises and all their glory! This is episode 12 of a 10 part series I’m calling 10 things Javascript Developers Should Know But Probably Don't. Enjoy!

[@onlineaid]

Amazing series :)

[@DanielNetSet]

12 out of 10? thats a out of bounds/stack overflow

[@davidhusted817]

You promise 10 episodes but now in 12 😂😂

[@kiranrega10]

Which js compiler are you using?

[@IntrinsicFlake]

I’ve been watching videos for years trying to make sense of Promises, and while I got through it, I’ve always wanted to come back and really understand them. Your video turned the light bulb on for me. Wow! I had to tip you for the help! I appreciate it so much! Definitely subscribing!

[@ColorCode-io]

That’s so great to hear. Thanks for sharing.

I am a 15 year old learning front-end development and struggling with promises. After 3 days of exhaustion I found ur video and finally got the whole concept. Thank you for this masterpiece 😍😍

[@AriKhuu]

I'm so happy to be finding your channel I want to cry. Impeccable production. Clear examples. Perfect pacing - not too fast, not too sluggish. Detailed yet very follow-able explanation. Funny host. thank you thank you thank you.

[@ColorCode-io]

Let’s cry together

[@MatthewWilliams-1212]

As a lead engineer I have to say, these are by far the best tutorials for javascript on youtube. Fantastic for mentoring junior devs. It baffles me how this channel doesn't have more views!

[@ColorCode-io]

That's ok! Numbers go up with time :)

[@AJD...]

Been watching your shorts for a while, decided to hop into your channel and this is the first video I watched. Holy hell the quality of your videos is mind blowing. You put so much effort into edits and your explanation is very planned, with a set preordained path which makes the most sense. You've got a new sub.

[@ColorCode-io]

Thanks AJD. Very nice of you.

[@abahiduh3246]

I have watched the best vidoes of Kyle Simpson, Tyler McGinnis, Tony Alicea, colt Steele, Jim cooper, Aksay, Ania, Maximilian, Sasha, I can go on and on.... I spent A LOT of Money just to understand. I have watched ALL YOUR VIDEOS. I can assure you that this explanation got.YOUR EXPLANATION of SIMPLIFYING THE CODE before refactoring in simply the Best. Your tutorial is AMONGST THE BEST THREE for me. THANK YOU, THANK YOU, THANK YOU.

[@ColorCode-io]

Thank you so much. This is very encouraging to hear.

[@lemonbubble1243]

3 days ago I wanted to watch just this video but the title made me look for the whole series, and I knew that to understand better I needed to watch the previous episodes, and OMG I'M GLAD I DID. I feel I have like a super knowledge now, EVERYTHING MAKES SENSE NOW!! I don't know how to express how grateful I am!! I'm so excited because you cleared all my doubts about promises and not just promises, now I understand Objects() way better! THANKS!! Waiting for your master class!!

[@ColorCode-io]

Glad to hear it! Full course coming soon.

[@Gargantuan_Inferno]

Why does youtube algorithm hide such gems from the millions who would have subscribed had they been recommended such videos❤ Would handsomely pay for such quality

[@ColorCode-io]

♥️

[@aleksazlatkovic4663]

What a charismatic person you are. Good Lord. I started the video knowing nothing about Promises and I am finishing it as an absolute pro. Thank you for going into detail.

[@ColorCode-io]

Thank you. Made my day.

[@神キラー]

i can tell you put a lot of passion and effort into your work bro its inspiring

[@Javier_Corado]

I come from a C/C++ and Python background, because of my current job I've been struggling with JS concepts, definitely these videos have helped me a lot, thanks for putting quality content available for everyone!

[@ColorCode-io]

That's great to hear. Thanks Javier.

[@AnastasiiaSnihur]

Now I know why I enjoy your videos so much! It's not just because of youre sense of humour and vibe, but also because of the bg with the Sade album cover😍It's a perfect match for my preferences!

[@ColorCode-io]

Great catch! 👀♥️

[@kimashiidan]

Cannot believe I'm watching this for free, you are the goat

[@ColorCode-io]

Thanks

[@xClown55]

There aren't many video's that are 30+ minutes worth rewatching, but this one certainly is. Nice video

[@vighneshs416]

I stumbled upon your channel from a random KZbin shorts. I am very certain that soon you are going to be a lot of people's go-to channel for Javascript (Or anything that you make content on). The effort you put in to make the concepts intuitive is just top-notch. And I guess it is very evident from the other comments as well. Thanks for the effort you are putting in man

[@blaqhakym]

Exactly the same for me. Looks like I will be here for a while. I'm hitting sub right away

[@ColorCode-io]

Thank you both! Welcome aboard.

[@whathuh6965]

I must tell you; that was exceptional! I've been learning JavaScript for 4 days and I'm already up to Async and this helped a lot.

[@ColorCode-io]

Glad it helped!

[@rokesby]

Thanks for this explanation. I appreciated you typing up the code 'by hand'. This 'slowing down' enhances my learning and lets me type along with you. Well done!

[@ColorCode-io]

Glad it was helpful!

[@erickchavez4551]

I really like how your examples lead to real life situations and at the end it doesn't seem that complicated. Thanks!

[@ColorCode-io]

Thanks!

[@johnnya246]

A very underrated channel. I like your style of teaching! Thank you for the content! Keep up the good work!

[@ColorCode-io]

Thank you

[@mashmixture5662]

Learn alot from ColorCode in just one month. Such an amazing content. The way you explain things is very very very interesting and funny. *Best JS channel* on KZbin. Thanks for such a premium content. Please deliver more.

[@ColorCode-io]

Thanks a lot

[@strangelight159]

5 minutes into the video and I can already tell that you are criminally underrated. Subbed

[@ColorCode-io]

Hah thank you

[@guy_roh]

Thank you so much for making an actually apprehensive video that normal people can understand, explaining the why's and how's in a much better detail than a lot of other videos I've watched! Subscribed and added this to my favorites in case I should I need it in the future! 👍

[@ColorCode-io]

Thanks Guy!

[@nikolanovakovic4150]

Brooooooooooooo 🎆🎇❤🧡💛💚💙💜 first of alll, love your humor, second of all amazing content struturing it is so well organized an succinct and i will do what all the other people in the comment section did compliment how good your videos are. much love !

[@ColorCode-io]

Thank you so much

[@rjerez]

Great work Sina, this is a subject that a lot of people seem to get wrong on interviews. Now I can refer them to this video. 👍🏽

[@ColorCode-io]

Thank you Ronald for your support, always!

[@BitWizCoder]

This is the first time I'm seeing this guy, 30 seconds into the video, and I had to subscribe. Thanks for the video and the fun!

[@chaoticthundergod3368]

Thank you for this video. Leaned a lot. I was learning about promises a year ago, didn't understand much so skimmed through it. But now i can explain to others what a promise is.

[@ColorCode-io]

Wonderful!

[@msunrl8577]

24:28 u so right about repeating and coding from scratch again and again, this so important to memorize and practice some hands on great tutorial, thanks

[@ColorCode-io]

🙏

[@Walid-Sahab]

How much effort you put for a single video other KZbinrs don't even put to build their whole channel.

[@ColorCode-io]

Thanks!

[@Mr_Pack]

you're the best of 7 videos about promises I've seen

[@ColorCode-io]

✋✌️

[@BrianMurithi-k7t]

Lot's of gratitude from me here Js Master, this series is really impacting me...

[@ColorCode-io]

Glad to hear that ♥️

[@mansoormohmand5852]

I have seen lots of videos and tutorials but never use this topic of promises in my coding because of the bad and hard explanation, but now I am pretty sure I can use and refer to this great explanation ever, thanks a lot

[@ColorCode-io]

👍

[@m47h4r]

29:10 A usecase for passing in onError in the .then() is to provide fallback data. For example, if fun1 rejects and then if the onError returns some data, then having fun1().then(fun2, onError).then(onSuccess) means that the onSuccess function will always receive some data, either fun1 resolves successfully and it's all good and well, or onError happens and that provides a fallback value so that onSuccess can always assume it has some data.

[@saikumar8186]

Until now, I have been hearing about promises but the way you explained has cleared the concept and become confident to proceed with JS coding. Looking forward for a Javsascript course from you.

[@ColorCode-io]

Glad to hear that

[@renzodiaz5996]

30:21 I can't believe Sina missed doing a "finally" pun when he literally was about to explain the "finally()" method. PD: Awesome video man! You teach us, you entertain us, you are a rockstar!

[@ColorCode-io]

You're right. What a missed opportunity.

[@theshtig4218]

GOATED video. This will be the last promise video I ever watch. Thank you!

[@oilybrakes]

You explain stuff really well. I will watch lecture 11 and 12 again before going to 13 and take notes of stuff that I understand so I can call it back to memory with clues my brain considers the most helpful. But even now, there were moments of enlightenment along the way... But I already forgot😅😂

[@ColorCode-io]

Glad to hear it!

[@mikeyim9597]

Glad I found your channel. It's the best explanation of the Promise and Async Await. Can you please do a series on the same topic for database CRUD? Thank you.

[@ColorCode-io]

I'm considering doing one on CRUD operations with Firebase.

[@xenocampanoli815]

BTW your "do it yourself" admonition reminds me of the advice at the beginning of all the old Charles Berlitz language tapes where he said: Read it, Hear it, Speak it. He may have also said "Write it" sometimes, but his point was memory reinforcement that is as functional as possible.

[@ColorCode-io]

🙏♥️

This is by far the best explanation on the topic I have been able to find, and I must say I love your other videos as well. Love the production quality too, what is the recording software you're using, looks really slick?

[@ColorCode-io]

The animations are all done by hand. The screen recording is just basic QuickTime.

32:10 In the real world example you have two .then's inside of the Promise's callback function. Why would they still work inside of the Promise? Does the catch() function already return a Promise?
