This is the best explanation of observables as it removes the confusion between promises and observable. this video also answers most of the basic interview question on observables.
Hello sir .my mind is blown by your calm explanation. Thank you its a very good tutorial .i am watching your angular full series .whaterver the concepts i was expecting all of those are here.i am happy .keep up the good work.
Great tutorial! I think you explained everything well and I liked how you did a little review of async JS. I'll definitely have to check out more of your videos
excellent explanation. l am really thankful to you . you save my time. also wanna tell you very important point about your speech. you have a very calm explanation and this help us to take notes and to digest the knowledge. do not change this style, this style carries you to success
The best thing about this course is creating separate project for separate concepts so it's easier to understand and practice if we want to brush up one particular concept. Amazing vidoes. Thanks a lot
Sir I want fetch the data from data service once and use that data across all components. But I want to persist this data in run time without using NgRX or local storage. What options do you recommend in this scenario ? Thanks in advance.
Good overall tutorial, however in the beginning you mention javascript is single-threaded, but then you refer to a "background thread". There is no background thread in javascript. Simply a queue which the single/only thread reads sequentially.
Your way of explaining is great in my opinion. You explain what, why, how to. Most importantly you know there are similar concepts, in this case it is Promise. You compare to point out the differences. I want to know why not compare with Async Await too??? Means in Angular we can’t use?
First of all thank you very much :). Angular is a JavaScript framework...so you can use all the concepts of JavaScript in Angular, including async / await. But since the basic requirement of learning angular is to have basic knowledge of JavaScript, i assume that viewers are already aware of the concepts of JavaScript like promises, async / await etc. So, i try to cover only those topics which is related to Angular, unless it is really required, otherwise videos will become quite lengthy.
If we call an Api using observable which is default in httpclient in angular, then also all data is returned in one go. Can you explain how stream of data will be returned.
This concept(observable) is really hard to understand. As you declare myobservable = new observable((observer) {console.log("observer starts.. ) Observer.next("1") ... Observer.next("5")} } If possible explain the concept with some more realistic data let's say user profile data. 1) explain concept 2)implementation in angular
Very good explanation thank you! but I'm still not clear why do we need to return multiple observers? observer.next(1); observer.next(2); observer.next(3); What's the use case?
This guy really explained observable while everybody else just explains difference between observable and promise and move on. Kudos. Subscribed
This is one of the best videos on observables I have seen.
True 💯
Very true😊
Perfect example. Amazing. I have been searching for this answer. Now I became a observer for this channel :)
I have watched so many videos and visited so many websites, but none of them provide the clarity of this concept. Thank you so much...
Your explanation of the differences between promises and observables is outstanding and unrivaled.

This is the first video were I properly understood what an Observale is

So wonderful explanation about oveservables which I used for a while but still didn't know the details. Thank you again!!
Your understanding of this is akin to the creators of the concept.
Learnt many things in few minutes
Grand master,Fantastic 👏

Wonderful lecture ,clear the whole concept. Thank you so much ,for this amazing series.
One of the best video on observables that one can get
This is one of the best videos on observables I have seen. kudos
Nicely explained! Thank a tonn man
Great class 👍👍, thank you for explaining so clearly so any one can follow
Very clear and concise explanation. Thank you !!!
Great Explanation, happy I got this video, thank you
You explained THE POINT! Thank you a lot!
Great job. Your teaching skill is awesome!!! Good luck!!!
Was really confused about observables, this video was amazing at explaning it in a simple way. Thank you!
I really liked the explanation! Thanks a lot!
Pretty clear explanation, awesome!
nice explanation, keep working
Excellent explanation.
Very well explained Sir ji..all my doubts clear. Also got subscribed. My unfortunate that found this channel late.
Very clear and helpful !!
Thanks you
Perfect explanation!
Well explained! Thank you
Very clear and very useful... thanks
Great video
Superb explanation 👌
Nice explanation
Best teacher on youtube. I watched a previous video on observables and couldn't understand anything. This video explained things clearly. Thanks.

ty, this was an amazing video
great explanation!
Excellent explanation !!!
is it possible to implement pathlocationstrategy and hashlocationstrategy in a project at time?
Best tutorial
you really deserve 100k subscribers
How observable work on http calls. As you said it streams data..can you explain this with http call?
Excellent drill on observable..
Nicely explained
Javascript ajax call will executes async right? What is diff ?
Best explanation
big up bro! hudge!
great one thank u
beautiful explaination
Good overall tutorial, however in the beginning you mention javascript is single-threaded, but then you refer to a "background thread". There is no background thread in javascript. Simply a queue which the single/only thread reads sequentially.
well explained
Good explanation. One question though. If observer is a consumer of data a.k.a subscriber, why does it emits the data?
Your way of explaining is great in my opinion. You explain what, why, how to. Most importantly you know there are similar concepts, in this case it is Promise. You compare to point out the differences.

@@procademy can you please make video on testing please in angular

Excellent
thank you from Brasil. You helped a lot! Just a question: if The server send a list as an answer does the observer still treats it as chunks?
No, in that case it will emit the whole list as one chunk
Thanks
first time to know that when someone says Subscribe ( 6:47 ) the subscribe button's borders does some effects
Keep going
thxs 😘
Great! Lecture again 👍
Sir,Is it necessary to learn Rxjs? In the future , you are going to cover about rxjs library?
It is not necessary to learn RxJS in order to learn angular. However, I will surely create a complete series on RxJS in future.
Thank you sir@@procademy
Wow.

This concept(observable) is really hard to understand. As you declare myobservable = new observable((observer) {console.log("observer starts.. )
Observer.next("1")
...
Observer.next("5")}
}
If possible explain the concept with some more realistic data let's say user profile data.
1) explain concept
2)implementation in angular

Very good explanation thank you! but I'm still not clear why do we need to return multiple observers?
observer.next(1);
observer.next(2);
observer.next(3);
What's the use case?
For example, fetching an array of data with fetch API and return each element with next
They're not returning multiple observers. They are just streams of data being emitted out of the observable.
alal vera
Observable returns data bit by bit okay
"ok"
"ok"
"ok"
you repeat the word "ok" as a broken robot...
only that was annoying, out of that.. good video
You explanation is quite nice.
But you could work on your heavy accent.
Does it matter? You did understand it right??
He's Indian. So he has an Indian accent.
Great video
