switchMap() | RxJS TUTORIAL 

Amazingly explained! The documentation is incredibly confusing on this but you cleared up all of my confusion right away.

I broke my head whole day to understand Switch map..google also did not help me ..most of the explanations were literally confusing..luckily I got to watch ur video..Thanks a lot for ur excellent explanation..

Thank you Max for making these videos on Rxjs, there is a dearth of clear cut info availability on the internet. I am here after your angular course on Udemy ! I learned a lot from it. Thanks again!

switchMap() is very complicated to understand but with your explanation, you make stuff easy, thank you so much.

I have just finished watching 8 out of 11 wonderful videos on observables you have made. Could not find such explaination anywhere on internet. You have made this subject easier. Thanks @Academind! Keep up the Great work!

A lot of the rxjs stuff hurts my brain. This video is really helpful and is possibly the only clear explanation I have found. Keep doing what you're doing.

This is the first explanation of switchMap i've actually understood. Thank you!!

I was looking to find an explanation to finally understand the difference between mergeMap() and switchMap(). I think now I do. Thanks!

I have fallen in love with your french accent. French people are good teachers!!

Thank you for getting to the point quickly and not wasting our time, EXCELLENT!!!!!!!!

This course of rxjs is very important to approach with ngrx, thank you Maximilian and keep up.

I like Max explain it straighforward and easy to understand

You have great videos about rxjs that are easy to understand and make the life of a developer easier.

Thank you. It solves my problem in nested observable on angular auth guard

I have been searching for a switchMap() explanation for awhile now and thanks to you I finally understand this operator. Thank you so much!

Thanks for the explanation. Minimal and simple, just what you need to understand switchMap.

I was in trouble with this operator. Thanks a lot man. It cam in handy at the moment. I am subscribing you right away.

I LOVE YOY GUY! Last night, i no understand nothing about that, but now, i understand very good the switchMap operator. Thanks man!

Very clear video thank you. I know its not HD, but the content is HD.

can i apply switchMap to my wife's repeated arguments

You're a godsend Max. Thanks!

Incredibly clear explanation. Thank you!

Ghost of Rxjs is no more . thq

No matter what I watch what i read, unless I watch your videos i don't get the concept completely. hahahaha... thanks bro.

Great tutorial - Finally switchMap makes sense to me :)

Thanks for your videos! They are so helpful! I'm developing for such a long time and really got stuck with all those RxJS stuff... your explanations helped a lot!

Excellent explanation!

Finally got what switchmap is OMG :O and can you please explain it with Angular 6 +

Very well explained!

Simpler explanation ever! Well done

Isn’t it confusing to type an observable in one way and then it returns something different than the type of the first? Maybe I misunderstanding this

Can I apply switchMap() operator more than once one after another?

the compiler tells me switchMap is not a property of Observable?????

Excellent explanation.

​ @Academind You are great tutor . Explained perfectly thanks for that.

man, i do really aprecciate your videos! Thanks for the help! Keep it up

Thank you sir, finally I understood switchMap !!

Very clear explanation - thank you!

Hey many thanks for the tutorials, quick question, what would be the best way to do if else in RxJS please?

Thanks, you made it so simple to understand... I am subscribing to your RU-vid Observable/Channel😅

I get that it stops old subscriptions, but how's it changing the values?

Great tutorial Max!

how do we cancel old HTTP request and subscribe to new which are not triggered from an event ?

Pretty clear explanation! Thank you!

Max i like your Rxjs series But Everybody is waiting for project based series including me. Stuff that we cant learn by reading documents. I would love to see large scale social network/shopping card based projects. RU-vid lacks those types of videos. Most of the videos are short and doesn't show the right way to do it rather the simple way to do it. If you can, please Make the concept or core technology based videos on Udemy and Project based videos on RU-vid. If they dont understand your project based videos you can always suggest them your Udemy courses.

I tried to execute in Angular 5 + typescript. but I've got this error : error TS2322: Type 'void' is not assignable to type 'string'. import { Component, ViewChild, EventEmitter,OnInit, OnDestroy } from '@angular/core'; import { Observable, Observer } from "rxjs"; import "rxjs/add/observable/interval"; import "rxjs/add/operator/take"; import "rxjs/add/operator/map"; import "rxjs/add/operator/bufferCount" import { Subscription } from 'rxjs/Subscription'; import { Subject } from 'rxjs/Subject'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.css'] }) export class AppComponent implements OnInit { /* @ViewChild("button") button: ElementRef; subscription : Subscription; */ constructor(){ } onDestroy() { // this.subscription.unsubscribe(); } ngOnInit(): void { let input1 = document.querySelector('#input1'); let input2 = document.querySelector('#input2'); let span = document.querySelector('span'); let obs1 = Observable.fromEvent(input1,'input'); let obs2 = Observable.fromEvent(input2,'input'); obs1.mergeMap( (event1:Response)=>{ return obs2.map((event2 : Response)=>{ event1['target']['value']+' '+event2['target']['value'] }) } ).subscribe( (combinedValue )=>{ span['textContent'] =combinedValue;console.log(combinedValue);} ); }

Where we gonna use this technically ? BTW Great series!

I had problem spotting differences between switchMap and mergeMap, until I found a quote on Medium: "So here’s the simple difference - switchMap cancels previous HTTP requests that are still in progress, while mergeMap lets all of them finish."

this is an awesome explanation - thank you

great explanation

Thanks, it was clear, but we would like to see these explanations in real situation, right now these operators been used intensively in Ngrx effect , it would be great if you could explain it with that.

Awesome explanation!! Help me a lot!!

Awesome... nandri it was so understandable... mikka mikka nandri

What are differences between MergeMap and SwitchMap ?

why didnt he use pipe function? I thought it was required to create chain operators

Such a great video! 🤘

Do swicthMap() exists on Subject and BehaviorSubject?

Best explanation , thanks!

Finally I'm starting to understand this switchMap thing :D haha... isn't it what a throttle design pattern does?

That was very helpful! Thanx a lot!!!

awesome explanation...

Thank You! Indeed it's helpful!

Super clear

Thanks a lot! It was very helpful.

Excellente explanation, thanks man keep on

good explanation

Can you do another video for exhaustMap, pls? :)

can you make a video about exhaustMap?

Keep up the great work !

'Rx.' where we can import in angular

great job max keep it up :) btw i love your angular 4 course on udemy!

So clear .. Thank you

Thank you.

It takes time to understand... I can't understand it for the first time

When we see creating real big projects? Example: Shopping Cart

i wish people would use real world examples for such topics.

Danke Bruder

I subscribed() to this channel

Buenardo

Love u man

is this deprecated?

Why didn't he put switchMap inside pipe???

Academind?

👍👍👍

thanks,

Still I have a doubt. I learned that switchMap() is a similar to map() except map() is applied Array object while switchMap() is applied on Streams or Observables. How Observable is similar to an Array... this is really confusing me. please some one help me out, Thank you

This is insanely overcomplicated. Love your tutorials though.
