The concise to the point no bullshit approach is really helpful.

Thanks again for a neat video. I always struggle explaining CombineLatest and flatMap in my videos but you explained well in less time. I would love to see more RxJs video from you Jeff, since I really appreciate your deep thoughts and I'm fan of RxJs

You have the most helpful angular content around.

Please keep making more videos like these. It's so straigt to the point, love it.

Thank you for all your vids. They help me a lot while messing with angular and firebase :)

Awesome explanation and real examples. Thank you for such a great video!

Just found this channel. What a godsend!

thank you so much. I had to stop and take notes here and there but I fully understand all 7 Rxjs concepts now.

Great presentation, great design, great audio, direct and to the point videos == subscribed!

Great and concise explanation.

Okay, so the motive is modern world coding through basic common sense. Explained simply. thumbs up!

Thanks for the excellent Explanation. You explained these concepts in simplest way. Thanks once again..:)

Thanks a lot, This kind of video really hard to find in youtube. Please do more about pattern / technique like this

Timeline of Events🕗 0:40 1. Important RxJS Methods - static vs. instance 1:35 2. Subscriptions - extract data from observables 2:42 3. Unsubscribe - prevent memory leaks 3:05 4. Map Observables - transform data in the stream 4:00 5. SwitchMap - handle data relationships 4:45 6. Combine Observables - two observables -> one 5:25 7. BehaviorSubject - share current data

Thank you for the great lessons!

You are the best channel and your website is helpful and helped me multiple times. Keep up good work

Great lesson!

Man, you are a sorcerer. thanks for an amazing video.

Great concept explanation. I had to listed some portions several times though, to comprehend,

Thank you! Great video!

concept wise , this is still valid in 2021.

Congratulations for 1 million subscribers Jeff We love you

Really nicely explained

Oh i love the background music with that great content

Hi, and thanks. You great man.

finally someone explained rxjs to me how I could understand it

Life changer...🔥🔥🔥

Excellent video

Thanks Fireship ❤️

My biggest takeaway from this: "....... THERE'S AN ASYNC PIPE??........ THERE'S AN ASYNC PIPE!! GRAAAAAAAAHHHHH!!!"

Thanks dude

Awesome..

thank you

Good video

Thanks to you, I don't fear RxJs anymore

Nice stuff

Thanks for the video! A quick question how can you paste the code ? do you use some quick paste tool?

What plugin do you use to paste code from the clipboard?

can you provide an example of using Observable groupBy on a Firebase collection?

I'm realy very interested about the usine of rxjs and firebase in my app i'm waiting for a complet course do u geve coaching ?

Can we get a revamp for new versions & cloud firestore?

What OS do you use? Linux Arch?

which theme you are using in your Visual code

I believe you skipped mentioning the major benefits of switchMap. It's counterpart mergeMap does as you explained. switchMap on the other hand cancels the previous request.

Hi Fireship, maybe it's a dummy question but what does the {{ (someObject | async)? .somePropertyOfObject }} mean? Is it some shorthand ternary operator or what? I've never seet it before. Many thanks.

I have no technical background just trying to understand how we would have handle data from API if we were not using this RXJS. angular is client side as far as i know and its not right to mix it with server side functionality might be violating Model View Controller architectural pattern.

Why not use just a variable instead of behaviour subject. We get current value in case of variables too right ?

Why did it take the community of us programmers so long to use observables/streams/realtime dataflow pervasively? Excel demonstrated that it is a good idea years ago...

Niceone

great and neat but way too fast for me lol

I'm probably one amongst few. But I actually prefer you talking slower and in a monotone voice, it's easier to follow

@2:44 I thought that unsubscribing was unnecessary for Observables that are finite/resolve. Like http requests for instance. stackoverflow.com/questions/38008334/angular-rxjs-when-should-i-unsubscribe-from-subscription

This is great stuff, but your audio is way ahead of your video... the description of the attributes are done before the code is even displayed, and when it is displayed it disappears in a flash (6:40). Would be nice to slow it down a bit and not seem like you're rushing out the door.. even your exit music is playing before you're even done with explaining everything. I just feel like you want to wrap this up before it's even started.

Like and subscribe... but don't forget to unsubscribe().

This looks so easy... firebase 9 feels awful, or the docs are awefull... I can't tell.

5:14 you have mistake. CombineLatest on two streams is gonna return pairs of [[cat, dog] , [cat, dog]....] instead of plain array. so your ngFor is not gonna work as you have shown

I can't understand anything, may be this video is not tend for beginners!

very unclear

Never ever subscribe in the component and assign dogs to this.dogs. 99.999% of the time it should be handled with async as cats was

U didn't use the map operator from RxJS. I think u used the map operator from vanilla JS and not RxJs.

thank you
