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?
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
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
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.
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
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.
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.
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.
