I've reached the point where if any topic is presented as seemingly impossible for a starter to understand, I just add brad traversy to the end of the search.

Most of the times I watch your videos, it’s like a treasure hunt for me. I know 95% of what you’re about to share, but I love learning that 5% that’s new! And it’s always there! Your style is so stupidly simple that it’s brilliant. Don’t change a thing. Thank you!!

[@denisfrolov242]

Excellent! Simple, plain, straightforward. Great job bud!

[@TraversyMedia]

Thank you :)

[@sutirthamarjit]

The beauty of this video is - No Complex Term, No Complex talk,only very straight simple demo. Easy to learn. :) Great Video.

[@billbortkevich2300]

You, sir, have a talent to present complicated context in q very simple and digestible way. Thank you

[@ajengwall9181]

Thank you so much for this. I've been trying to wrap my head around this library for too long. Great tutorial!! :D

[@pascallussac6917]

i'm now watching and learning rxjs, as old as this video is, it's still dope!

[@lucisetumbrae]

Super video. Finally I have a fundamental understanding of Observables that allows me the flexibility to seamlessly use them as part of code. Thanks much for the effort.

[@HungBuiOfficial]

Rxjs Observable concept was really bugging me until watching this video. Simple & easy to follow.. Really well done. Thanks

[@ganqqwerty]

Very logical and step-by-step. As soon as you started to talk about the next example I already knew what it will be, because I wanted to try the same thing. Great-great-great video, gonna go and buy myself a course. The only thing: I didn't set up the environment, instead I took the existing plunkr where rxjs is already connected.

[@Algebrodadio]

Dude - I so needed this. Thanks.

[@koolmo]

What a great video.. Thank you for your step-by-step intro to RxJS.

[@byassine52]

Great video! I found it just when I needed be when the RxJS documentation was difficult to understand :)! Thanks a lot!

[@algoforge24]

Awesome! Everything I needed. Thanks Brad!

[@atticsolutions1476]

Great stuff and very helpful to get an overview of RxJS. Thanx!

[@paul-razvansarbu2067]

[@davidjustice2323]

Your voice makes my day! Love ya bro

[@raistlinmajere2257]

Good timing, Brad! I was just watching MEAN ToDo's on Udemy and wondering hat the pointer actually did..... Thank You for the knowledge.

[@vineetbirlasoft]

Thanks for explaing Rx in a verysimple way keep posting..

[@nzjemountfort]

Thank you - You have clarified alot of context around this

[@rahulsingh-px6vo]

Very nicely explained. You are always excellent Brad. thanks TraversyMedia :)

[@spaxxkey5936]

this has to be the most under rated RXJS youtube video, it should be like a BILLION views by now, i strongly suggest anyone battling with the "Observable stream enigma" to watch this.. Thanks BRAD

[@redsnakeintown]

Very clean presentation and informative...A trick to comment is to the select the lines you want and hit Command+/ or Ctrl+/ (Windows)

[@franklinbacayo1519]

nicely laid-out, good job! thanks

[@dallinparker2387]

This helped so much to better understand RxJs! thank you.

[@olehivaniuk1441]

Thank you very much! It was informative and pretty simple for understanding!

Extremely good vedio, as it helped me to understand observables in a best manner.....!!

[@shuaibird.official]

I'm so interested about this library. It looks so cool

[@gamatossian]

Great work, keep it up! Much appreciated.

[@AustinLovell]

I needed this. Thank you!

very nice tutorial and easy to understand, thanks a million

[@shikhadeepak82]

Thanks.... Very nice video. I learned a lot.

[@carlospoon6422]

Great Brad! you can read my mind too - :o) I had RxJS & Bacon.js down on my list. Loved your last one on Ractive.js, so bought your 4 hour course too, plus a few more... THANKS again !!!

[@carlospoon6422]

Brad, Any chance you might do a crash course on Cycle.js ? - It would tie in well with you RxJS course

[@albertogarcia1101]

Thanks Brad! Its was very useful.

[@bigggjimmm]

thanks to u i'm getting some from all this Observed mess !!

[@tuviakhusid4320]

Very useful video. Thanks, guys!

[@surajitdas6555]

Very simple, plain and superb explaination provided which clears all doubt of mine. Suggestions: Most of time went in typing, would have great if would have used some intelligence and keyboard shortcuts. :) Really worth to spend 1 hour time to understand these concepts with very simple examples. Thanks a lot, really appreciate your effort.

[@LethiuxX]

Very helpful! Thank you, sir!

[@PrasannaBhatK]

Good Presentation. Clean and Easy

[@Gatsbi]

That' was very nice and clear. Subscribed

[@amoghasoda]

Very valuable explanation! Thnx a lot!! :)

[@smartinsantos]

Perfect! keep up the good work!

[@isroiljohntolibov6057]

Awesome tutorial helped a lot. I wonder if you can make a redux-observable and redux-symbiote course please

[@OmarAMRANI]

Awesome presentation!!

[@ghanimalmarzouqi3277]

Thanks Brad .. This was very helpful ..

[@scottsmyth3251]

Great intro video, thanks.

[@jhkmatthews]

Thank you! Very helpful.

[@wdhuntertv3850]

top notch. great work

[@girish3643]

Brilliant explanation Thank you:-)

[@HugoRamirezSoto]

Thank you Brad, this is a great tutorial. Only one comment, I had to increase a lot the volume of my speakers, I couldn't hear you well enough. Maybe you should increase the volume of your microphone.

[@ameenu]

You made my day :D

[@joannagoda2245]

Great job. One question: you mentioned double subsription may cause problems in some cases. What are those cases?

[@korbendallas1210]

that's awesome...thanks, bro!

[@vamshi1741]

30.41 why did you call it a Map? Where are the key value pairs? Isn't it a 2 dimensional array? I'm kind of new to the Map data structure. Thanks in advance.

[@christopher96]

Great course!

[@jorgesepulveda8380]

when I type webpack -w on the terminal after installing all with npm install, it returns something like the order not found. Any idea?

[@Indicestudiocl]

In your proyect folder run: ./node_modules/.bin/webapck ./node_modules/.bin/webapck -w And dont install webpack globally

[@memecommandomike4659]

webpack needs to be installed globally for the cli command to work, you can get this installed with "npm install -g webpack"

[@vladislavnikolov322]

Very nice, thanks

[@madhujohn9018]

Thanks for great video :D

[@MatkatMusic]

at 16:03, how are the different anonymous functions differentiated? There's no data type for the parameter. does the subscribe() method require 3 unique functions in a specific order as the arguments?

[@Skaryon]

Late reply, but yup. It's just a specific order.

[@manufacturingvault7626]

Awesome! I learned alot. u da man

[@pianoflow9041]

Awesome video!

[@nashah25]

Nice... Thank you..

[@lindazhong1721]

Really great!

[@greatotool]

thanks a lot !!

[@najibla]

Thanks! Great video for beginners. The only issue is that it was so slow that i had to play it in x2.

[@Wallrunning]

Thank you!

[@jordigonzalez6672]

Thanks, very useful

[@nityakrishnan2178]

Superb!

[@user-xz8vj8ib3m]

thanks, good job!

[@vitaliypetruk5162]

thanks

[@omarelsawy7562]

Great job

[@myvue4587]

Great.... good video 👌..... thank you

[@luizmeier]

Excellent.

[@snakepat332]

1:06:11 Using "merge" instead of "concat" is producing the exact same sequence on this example. Maybe using a service API calls would make the difference more explicit ? Otherwise, very useful video I really enjoyed watching and following along with. Good job!

[@surajitdas6555]

Snakepat In merge both observables will run concurrently but in concat it will run sequencially. Thats the difference as per my knowledge and I think thats true. :)

[@pawankumar9605]

nicely explained

[@newcaiosantos]

GREAT!!!!!!!!!!!!!!!!!!!!! Thanks a LOT!

[@hpacdev6170]

thanks you bro this is best tuto

[@ManishSharma-qz7nk]

thanks man!

[@abdallahbedir32]

Thanks alot

[@rubgud9903]

It's a good video!! thx!!

[@albertpatterson8164]

I like this.

[@danvilela]

Very good! But why that other ways of doing it are not correct?

[@FredoCorleone]

John... Tom... Shawn! Shawn! Shawn! Shawn! haha That glitch from Heavy Rain

[@fflorin1994]

I have a problem with live-reload, actually the content on page remains the same. I use VS code and Chrome

[@kuldeep1950]

out of curiosity at 20:17, why the output is not... v vg vgb is there by default throttle for event observables?

[@costagmc1]

great, even after 5 years

[@cristianscript5649]

what's the difference between switchMap and add another map function below humm ??

[@paulovinicius9940]

For those in November 2020: const sourceInterval = interval(1000). *pipe* (take(5)); sourceInterval.subscribe( x => { console.log(x); }, error => { console.log(error); }, completed => { console.log('Completed!'); } );
