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!!
Excellent! Simple, plain, straightforward. Great job bud!
Thank you :)
The beauty of this video is - No Complex Term, No Complex talk,only very straight simple demo.
Easy to learn. :)
Great Video.
You, sir, have a talent to present complicated context in q very simple and digestible way.
Thank you
Thank you so much for this. I've been trying to wrap my head around this library for too long. Great tutorial!! :D
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.
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.
i'm now watching and learning rxjs, as old as this video is, it's still dope!
Rxjs Observable concept was really bugging me until watching this video. Simple & easy to follow.. Really well done. Thanks
Dude - I so needed this. Thanks.
Very clean presentation and informative...A trick to comment is to the select the lines you want and hit Command+/ or Ctrl+/ (Windows)
What a great video.. Thank you for your step-by-step intro to RxJS.
Great stuff and very helpful to get an overview of RxJS. Thanx!
Great video! I found it just when I needed be when the RxJS documentation was difficult to understand :)!
Thanks a lot!
This is very well explained.
I was very intimidated by the subject, helps me a lot
Thank you!
Good timing, Brad! I was just watching MEAN ToDo's on Udemy and wondering hat the pointer actually did..... Thank You for the knowledge.
Awesome! Everything I needed. Thanks Brad!
Thank you - You have clarified alot of context around this
nicely laid-out, good job! thanks
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
Very nicely explained. You are always excellent Brad.
thanks TraversyMedia :)
Your voice makes my day! Love ya bro
Thanks for explaing Rx in a verysimple way keep posting..
Thanks, its simplicity made it very best.
Greatest course about RxJS, thanks so much!.
This helped so much to better understand RxJs! thank you.
Powerful examples!
Thank you.
Was really helpful getting a quick overview, Thanks !! :-)
Crystal cleared explanation. Best video I have ever seen for RX-js.
Thank you very much! It was informative and pretty simple for understanding!
Awesome and simply explained. Good job mentor
Super simple and clear and awesome tutorial!!!!!!
I needed this. Thank you!
Thanks, it was really good. Keep doing great videos.
Great work, keep it up! Much appreciated.
Thanks.... Very nice video. I learned a lot.
Best explanation on YT on this topic !!
I'm so interested about this library. It looks so cool
Thanks Brad! Its was very useful.
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 !!!
Brad, Any chance you might do a crash course on Cycle.js ? - It would tie in well with you RxJS course
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.
thanks to u i'm getting some from all this Observed mess !!
Extremely good vedio, as it helped me to understand observables in a best manner.....!!
Awesome presentation!!
very nice tutorial and easy to understand, thanks a million
Good Presentation. Clean and Easy
Perfect! keep up the good work!
Great intro video, thanks.
Very helpful! Thank you, sir!
Very useful video. Thanks, guys!
top notch. great work
Very valuable explanation! Thnx a lot!! :)
That' was very nice and clear. Subscribed
Thanks Brad .. This was very helpful ..
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.
Thank you! Very helpful.
You made my day :D
Brilliant explanation Thank you:-)
Great course!
Awesome video!
Awesome tutorial helped a lot. I wonder if you can make a redux-observable and redux-symbiote course please
that's awesome...thanks, bro!
Thanks for great video :D
Awesome! I learned alot. u da man
Thanks! Great video for beginners.
The only issue is that it was so slow that i had to play it in x2.
Really great!
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.
Superb!
Nice... Thank you..
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!
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. :)
Very nice, thanks
Great job
thanks, good job!
thanks a lot !!
when I type webpack -w on the terminal after installing all with npm install, it returns something like the order not found. Any idea?
In your proyect folder run:
./node_modules/.bin/webapck
./node_modules/.bin/webapck -w
And dont install webpack globally
webpack needs to be installed globally for the cli command to work, you can get this installed with "npm install -g webpack"
nicely explained
Great.... good video 👌..... thank you
Thanks, very useful
great tutorial. thanks man
James Johnson hey
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?
Late reply, but yup. It's just a specific order.
thanks you bro this is best tuto
Thank you!
Excellent.
GREAT!!!!!!!!!!!!!!!!!!!!! Thanks a LOT!
Great job. One question: you mentioned double subsription may cause problems in some cases. What are those cases?
out of curiosity at 20:17, why the output is not...
v
vg
vgb
is there by default throttle for event observables?
thanks man!
what's the difference between switchMap and add another map function below humm ??
thanks
It's a good video!!
thx!!
John... Tom... Shawn! Shawn! Shawn! Shawn! haha That glitch from Heavy Rain
I have a problem with live-reload, actually the content on page remains the same. I use VS code and Chrome
How is a stream different from state, like in react?

Very good! But why that other ways of doing it are not correct?
how can you do output.html('h1'+bla bla bla) in Angular?
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!');
}
);
$.ajax already returns a promise with done and fail, why we convert to promise. how do they both differ??? is it only coz observable can only take a promise object as parameter???
