man i love your videos.i cant stop watching.i think you are the best teacher i have ever seen on youtube

[@academind]

Awesome to hear that, thanks so much Muhammet!

[@raylawlor4887]

This is probably the best explanation of RxJS I've seen on the web. Many thanks!

That's just fantastic to read Ray, thank you very much for your great feedback!

[@armaandhanji2112]

Wow, thanks a million for your awesome feedback and for your absolutely fantastic support here and on Udemy Shaun! YOU are the best :)

Any TIme You've helped Me the past few years gain the knowledge I needed to become truly successful with the knowledge you share. My faimly and I thank you!

[@chittaranjansahoo9503]

Really a nice tutorial with very clear explanations on each concept. Great job Max.

[@academind]

Happy to read that you liked it, thanks a lot for your awesome feedback!

[@netssrmrz]

Good video. Took me a while to find one that explains why I'd use this. Still not a compelling argument though. The throttling example just showed me how a five line function can negate me needing to add yet another dependency on my project. And the funnel... Good analogy but again, I can't think of any programming problem I have that would be fixed by a funnel.

[@johanchouquet2872]

Thanks a lot Max for this great video ! An idea for your next videos, would be to do one video for " the logout functionality" in the "Angular/Vue with Laravel Backend", then to come back here in RxJS and show how to build a reactive header of a web application, using RxJS and Observables, with an avatar of the user being loggedin, then logged out etc..., to show how to share state of the application. The use cases are: 1) across one browser window, 2) one tab, 3) several tabs, 4) several windows, 5) several devices. I believe that nobody has done it before (i would do so if i had the time ^^).

[@academind]

Thanks for your great feedback and the suggestion. Unfortunately, it's not that likely that I'll cover this because it's a very niche case. I'll have more videos about RxJS coming up though, so I'm confident there'll be some useful ones. And you never know - I might revisit either the Angular + Laravel app or build something new in the future where I then can incorporate (parts of) your suggestion.

[@GintsPolis]

You explain thease things so clear way... Well done!

[@burakd.2139]

Honestly, wish I had seen your youtube channel before digging deep and getting lost on your udemy courses. If I could have watched this rx/js explanation while watching other ionic 2 and angular videos it might be much easier to understand. Maybe they were linked but I missed them. Thanks anyways.

[@academind]

Happy to hear that these videos were helpful. Good thing is: You have lifetime access to the courses, so you can only go back and dive into the parts you had issues understanding before :)

@@academind So good I actually went on Udemy and purchased your Angular course ;)

[@LinusBenjamin]

Also (as a suggestion) I would love to see a video on NGXS (ngxs.io/) a new central state management library for Angular which looks amazing!

[@academind]

Thanks a lot for your support and for your suggestion. NgXS is pretty interesting and I'll definitely have a closer look at it. Thus far, I haven't worked with it too much to be honest but we'll see, maybe I'll cover it in the future (cannot promise it at as of now though).

[@zacharystockwell4766]

Anyone getting a reference error? "error" "ReferenceError: Rx is not defined at duyazifuzo.js:3:1"

[@ibnumalikmy]

Hi, if you are using the new rxjs which is version 6, they are doing it differently now. You can look at the updated code from the video here jsbin.com/yopocexopa/edit?html,js,console,output

[@Asha-se4wv]

Please upload something on Redux usage in Angular

[@killerdroid99]

are u high or something??

[@zaydraco]

Works with the same thing that qt, glibc does... on there are the signal/slots

[@zahidyldrm5625]

I would love to see you guys are making graphql videos.

[@academind]

A great suggestion! I can't promise anything but I'll keep it in mind!

[@SahharYoucef]

can use those videos to learn RxDart or there is deference between libraries ?

[@ОлегВолков-р5ч]

Hi, what is better to start first Angular or Rx.js ? Which learning curve is easier? Thanks

[@academind]

The two actually aren't alternatives. Angular is a frontend framework, RxJS simply a library adding one specific functionality: Observables. If you want to learn a full framework, go with Angular.

[@ОлегВолков-р5ч]

Thanks a lot.

[@frilansutvecklaren2062]

Doesn't Angular already have reactivity. Why use another library for that?

[@vikrantsingh47]

I am watching for redux-observables, is this still relevant?

[@alexk6745]

How about unit testing?

[@GabrielNemeth]

Hi Max, I'm wondering if you plan making a Udemy course about RxJs.

[@academind]

No, got no such plans. But I do plan to release more videos here on KZbin. I'll dive into different aspects and operators, so that might be interesting for you.

[@winterheat]

React weekly download: 20M. RxJS: 45M... why?

[@sanjayshr1921]

Video request: RxPy. Thank you in advance.

[@grcvgcvcbh6999]

Whats better to learn for future Es6 or typescript whats morecuseful

[@academind]

Definitely ES6 as TypeScript also uses that. And most frameworks/ projects don't use TypeScript. It's nice to know and I think it'll become more and more important but definitely don't go all-in on it. It's based on JS in the end.

[@hussainabbas1341]

[@shai2009]

[@OussamaBezzad]

Hello, Is there any alternative for VueJS ?

[@academind]

You can just use RxJS with Vue.js - it's a JS library, not limited to Angular :)

[@yash.karmayogi]

use it with laravel

[@academind]

How would I do that, it's a JS library ;)

[@yash.karmayogi]

but vuejs works with laravel

[@BrainBUG1231]

No, VueJS doesn't directly work wiith Laravel. What you want is to use `Laravel` for the Backend API and `Angular` for the Frontend SPA where you can implement Observables that can dynamically communicate with the backend.

[@deenriqo]

It is nice explanation. however the Use of RxJx in Angular is one of the reasons Angular is loosing ground to other Frameworks. It over-complicates things. Basically you can just listen to an event if you want to react to a change.

[@KonradZielinski]

Nice explanation of a terrible idea, sadly I need to learn it.

[@zidanelam]

Hi Blake Griffin

Whatever you keep in your mouth when speaking you better spit it out and speak normally

Mindspace Don't listen to him! Thank you for your courses!

[@AntonMochalin]

FnMTooL NIN Yes you're right in all you've said but he'd still better work on his voice because his voice isn't very pleasant so to speak. We're on KZbin and as I'm ok with your reply to me he's I guess is OK with my reply.

[@AntonMochalin]

FnMTooL NIN And speaking of free content there are ads enabled for this video which means the author gets a share of the ad revenue.

[@PS-dp8yg]

Anton Mochalin You cares!!! You still have access to free content. Nothing is coming out of your pocket or mine.

[@user-zb5jp4ti1d]

The key takeaway for me here is the 'funnel-like approach.' That is a great visual aid for Observables. Thanks Max. I am sorry for being cheesy, but you are to Angular training what the Sun is to the Earth.

[@academind]

Thank so much for your absolutely amazing feedback! :)

[@ben6]

for my own reference: Adds more functionality to functional programming, especially through the use of operators, which are built in logic mappers you can plug into the process.

[@robertojarzembowski]

Max(or anyone else), considering that arrow functions are unsupported by Internet Explorer(at least up to v. 11), is still possible to use Rxjs and maintain cross browser compatibility?

[@josecobos6105]

more real world example?

[@javascript_developer]

I understand the video but in my case why it keep saying 'arrow function syntax (=>)' is available in EST (use esnext option)

[@javascript_developer]

In my case I have a button and the function is being executed twice. Due to the both load and click event. How do I control the function to be executed only once when I click on button ?

[@SinaGilassi]

[@AdnanAhmed-Web-Developer]

You made it so easy. Thanks 👍

[@mikeandtherest]

I like the way you explain this things, but I would really like to understand why the throttleTime() function didn't work here. Because it actually allowed you to click the button more than once and after you stopped clicking it for a few seconds, when you went back on clicking it, it didn't work anymore. So something was off there, but the code looks ok. Thanks btw!

[@tabliqatchi6696]

He's just added "those visuals on his clicks in his video", if you pay attention, the actual effect of click "from his code" is what's gets printed on his console to the left of the button. I mistook those at first too.

How is this different from LoDash. Seems like you achieve it using lodash? Also different then knockoutjs?

Totally different. It's not a utility library (like lodash) - it's a library introduce a whole new way of working with (async) data sources.
