The best explanation I've seen on such a complicated topic with example. Hats off to you.

[zzzbyyy]

I have seen a lot of video tutorial like this ... but Max is definitely one of the few teachers with this ability to present everything in most logical and straightforward way possible no matter subject ... glad we have you here ... cheers !

Finally, observables make sense!!! Thank you so much Max for taking off a bit of the frustration on the tortuous path of Angular.

I'm learning RX for Java, and honestly, your explanation was the clearest out of all explanations on Rx I've seen, after shallowing hours and hours of videos without even understanding anything I found your video and in 20 minutes I finally got the whole idea on Rx, I hate to see pretentious people complicating their work with technical words and buzz that only themselves understand just for the sake of their own ego, and some of us programmers are pretentious experts.
Keep up the good work.

You've just cleared my fears with observables concept.
You sure know how to make things easier to learn.
Thanks

2023 and this is still the best lesson out there on you max

Now I am confident to explain the interviewer 😀😀 Thank you so much it’s simple n clear hats off to you . You are my Guru 🙏🙏

At first I was afraid that this would be outdated, being 4yrs ago but it's been an awesome tutorial. Looking forward to more.

I am from Argentina, I'm not a native english speaker but I understood everything you said, was an excellent explanation! Thanks so much!

I have been a fan of Max since long time. He explains any/all concepts in such a simplistic manner makes the learning job easier. Thank you Max!

Great explanation on a tough topic. Had to rewind around the 10 minute mark. Came up with this:
We created an observer object, with next, error, and complete methods on it.
We then created an observable:
1) with an anonymous function passed to its create method, and
2) with subscribe chained to it.
We passed our observer object to subscribe.
RxJS will perform some work on it,
then pass it as modified back up as an argument to the function we passed to the create method.
In that function leave a distinct variable as a parameter
so it can receive the modified observer.
The function we pass to the create method can then call next, etc.

it seems like people try to make these topics "sound complicated", but the honest truth is that its a gift to explain things well. great job bud.

[NickMaovich]

Oh wow!


I'm creating a series of knowledge sharing meetings on RxJS for my colleagues and I will definitely list this video in the resources!


Good job and very goof explanation!

[kiranraj]

Seriously, you explained it in depth with a very simple presentation. What a beautiful explination. Many many thanks.

[alburnto]

Thank you *so* much. I had kind of an irrational 'fear' of Observables, and this helped me get through the documentation way more relaxed. Thank you!!!

[dmitriykuznetsov]

Man, that was SOOOO helpful. That`s a really high-quality explanation. Thank you very very very much.

[jurikonradi]

The best explanations of observables, so easy, so logical. Observables have two problems: 1) you have to read them from bottom to the up ... and 2) bad documentation.

[islamway_to_jannah]

what i learned from this youtube channel is million times much useful from my 5 years CS college training

[eugenevedensky]

Thanks for the video. One can never learn too much about observables.

[azndoodle]

I agree with many of others here, very clear and explicitly explains every step of the walkthrough. Thank you for providing and anticipating everyone's mental questions and taking us through a mental thinking about this topic.
