RXJS Operators Explained with Examples: switchMap, map + More

[@neverbenbetter8225]

Originally, I was planning on going over examples in code, but I decided against it to keep the video shorter and keep the focus on vocabulary. I'm wondering whether making another video - one focused on code - would be helpful to anyone?

[@andredealbuquerque105]

For sure! The code would be interesting to get this as a view of how to go outside of the metaphor

[@neverbenbetter8225]

Thanks for the feedback. If you have any specific questions or if you were looking for something when you found this (and the last) video, let me know and I will try to incorporate your questions.

[@georgepagotelis]

In the end we need to code to put into practice

[@Asaloy]

Of course this would be helpful :)

[@vishay09]

Yes please at least basic examples for each scenario will be great help.

[@pouriadaki8586]

one of the best explanation of rxjs since I started to learn programming , thank you

[@liang3163]

The first man I found to be able to clarify these related terminologies, liked and subscribled!

[@HamzehExplains]

The best metaphor could be used in explaining different RxJs operators in such short amount of time! Well done!

[@hyukshin2387]

This is gold.. I was having hard time grasping what exactly some of these concepts are and with this.. all solved like magic. Thanks so much 🙏

[@landon.wilkins]

Sir, thank you for breaking this down. You made my morning.

[@ShanDev-be7qq]

The best analogy I have ever seen for the RxJs operators.

[@semperfiArs]

Best example of RXJS I have come across. Hats off

[@ameyakale3205]

I was just randomly looking to learn about Subject however I just watched the first part and was literally hooked. Really the best explanation I ever saw about the whole rxjs Observable

[@DodaGarcia]

This was really impressive, subscribed

[@giorgimerabishvili8194]

Definitely the best explanation I've ever seen! Absolutely amazing channel and keep up more Angular videos please

[@neverbenbetter8225]

Thank you. You know, the Angular videos haven’t got a lot of traction yet, which is disappointing for me, but maybe they just need more time to be noticed.

[@saianusha5979]

explaining with examples hits straight..loved it

[@zegollygosh]

I just stumbled on your videos yesterday and I have to say I really appreciate them! I've been a junior dev for about a year working in Angular mostly, and rxjs has always tripped me up. I usually just used the functions I notice that similar components use (mostly switchMap) without really getting what that actually MEANT, other than it took the data in so I could use it on the page. Sitting here having coffee before a meeting and listening to this has made a ton of difference and I plan on making visits to your channel a regular thing because you explain things REALLY well (the weather explanation is surprisingly perfect imo. There are so many moving pieces, like the meteorologist or the instruments they use, yet they all are relevant both in the example and in what they represent in the code). Thank you so much for this video and the other rxjs videos (and I'm sure I'll have more to thank you for in the future)

[@davidwildman4447]

I've been looking for something like this for months! First-time developer in my first job, and I've been struggling to understand observables from documentation and tutorial videos. This is what I needed - thank you!

[@neverbenbetter8225]

Awesome! Please, if you have any more questions, let me know.

[@SatyaRam2k14]

Why on earth, is this guy so underrated?????????????? WHY!!!!!!!!!!!!!!!!!!!!!

[@amsterdamamama]

This is genius! So quick and clear! Thanks!

[@n2productions]

Ohhhh mannn... I've been racking my brain at work for days trying to get a handle of observables and RxJS to use for HTTP requests. This series is truly GOLD! THANK YOU SO MUCH, definitely a follow from me :)

[@neverbenbetter8225]

That is exactly how I felt when a I was trying to figure this out!

[@parishare2750]

Bravo man! Thanks for this great explanation/examples. I will still have to brew a pot of coffee and listen to this 5 times but you definitely make far more sense than the documentation to me!

[@neverbenbetter8225]

Thank you so much! Glad I could help!

[@rembautimes8808]

This will make an excellent interview question. Thanks

[@RonaldJayBuayan]

best tutorial for beginners! you are amazing

[@dilipshelake803]

Nice way to explain the complex things. Thank you so much..

[@tonyx233]

this is incredibly well done, thank you for the series.

[@sweetnsourify]

Best explanation that I’ve heard. Thank you!! Will be checking out your other videos.

[@baluditor]

That was awesome explanation, thank you!

[@yarmab]

You are definitely good at the things explanation👏

[@sandeepchandupatla7832]

Superb explanation, very easy to understand 👏

[@naimeahmed1192]

You know what, I couldn't stop login to comment and like and subscribe after watching your explanation. Thank you man. I just become a fan of you :)

[@neverbenbetter8225]

I really appreciate that!

[@alfred7010]

In one word amazing

[@nauristisanchins9306]

Very Helpful content, as rxjs is a very confusing when 'observing' the documentation alone! Thankyou!

[@neverbenbetter8225]

I’m so glad to hear this was useful!

[@huntermyers1046]

Excellent video. Starting with a metaphor is super helpful, and I wish more documents could be written this way. Once that framework is understood, the technical details are so much easier to contextualize.

[@jorgen180]

Great example!

[@nikensss]

I really liked the way you explained both in Part 1 and 2!

[@neverbenbetter8225]

Thank you so much. If you are looking for more, I finally followed up with an examples video: kzbin.info/www/bejne/n6SsZ6Wmo7l8g6M

[@randomnamename1424]

Very helpful.Thank you

[@kokoyroy]

U are awesome. U helped me to understand rxjs.thank u so much dude

[@neverbenbetter8225]

Thank you so much. If you have any questions, please let me know. These videos are picking up more attention lately so I’m motivated to produce more content.

[@thimothelamoureux5718]

I love your explanations anx examples Ben. I think I'll have to watch this one a few times to really integrate the concepts with how I can use them

[@imriharlev5151]

Thanks for the good explanation 😁

[@hansschenker]

I like the way you explain the Operator's working with the Metaphor 'Weather Station', It would be an interesting exercise to try to explain all operators (almost) all operators on this Weather data pipeline by just using visual explanations, In your video I only concentrated on your visuals about the operator and did not read the text. Either text or visual but not both together (one weakens the other)!

[@anastasia3919]

Thank you very much for your work. It was very useful!

[@rviswak21]

Excellent

[@pbezanillat]

Nice video, very teaching

[@ansaardollie7584]

Incredible explanations. Thanks for the insight

[@neverbenbetter8225]

I appreciate your comment! Thank you for watching!

[@ddomingo]

Great analogy! This helped me understand the difference between concatMap and mergeMap. I think it would be nice to mention that this analogy is perfect for hot observables, but doesn’t really apply to cold observables

[@neverbenbetter8225]

Great suggestion!

[@riccardomassafaidatech]

Really, really helpful

[@MohamedSayed-xl7gu]

awesome explaining !!

[@craigiswayne]

This is great! thank you for your service. Using abstracted real life examples really helps, at least for people like me!

[@ujuzitek301]

Fantastic

[@dhyeypatel7449]

you are awesome sir

[@duckhorse2563]

Thank you.

[@ItcomserveDe]

this was a great explanation :-)

[@x11y22z33me]

Brilliant analogies. I am encountering rxjs and ngrx for the first time, and this helped my understanding a lot.

[@chrisfelix9065]

God bless you!

[@ahmedouyahya]

GENIOUS!!!

[@mirandamoralez6354]

Enlightning!

[@dotnetist]

Nayshh thank you for this

[@MG-wx8yx]

This video is 2 yrs old and I’m seeing it now!!!😔. I hope you doing well bro. Observables is the most difficult thing for me in Angular, but those operators are so useful.

[@goosemoose1213]

ty

[@hamzakamel5635]

I loved your way in explain as a story but i think what is the better show some code example, Thanks.

[@toddzmijewski6002]

What happens when combineLatest is used on the weather station but wind gauge never emits a value or fails to emit a value for a prolonged period of time. Are all the instrument values of the weather station required to analyze the weather or can the weather be analyzed based on a subset of instrument values from the weather station.

[@kjmoses8546]

I like literally everything u do .. And what microphone and camera name u use .. Just so i would one day have one..and i need ur suggestion .. Can i use them for short action movies

[@orleydoss3171]

Late to view... excellent explanation very easy to follow. Getting good base/foundation from this and other sources.

[@toddzmijewski6002]

The meteorologist combining insights from the source (weather station) would use a concatMap unless you want to cancel inflight insights and replace them. Furthermore, the withLatestFrom() operator has an observable as an argument. That operator does not provide access to the emitted value. It combines an emitted value with the another one from a separate, isolated observable that is an argument passed to withLatestFrom().

[@vanukurunagesh9051]

Hey. It was a great explanation. One of the best in fact. But it would be more helpful if you could add coding example at the end of the video.

[@neverbenbetter8225]

Thank you so much. I just posted an example video that piggy-backs on this one: kzbin.info/www/bejne/n6SsZ6Wmo7l8g6M

[@kmui6022]

what i dont get about rxjs. it is often used for async calls. but why? unless it is not using websockets we can expect only one incoming response? isnt an observable complete overkill here? for these simple predictable http requests it seems that rxjs is too complex. can someone proof me wrong pls?

[@sandeepguntupalli8482]

💖 from India will be nice if you explain with codes too

[@ricko13]

I got way more confused, thanks

[@goldfishbrainjohn2462]

When will you come back to make another video? By the way, has anyone said you look like Robert Pattinson?

[@msettecasse]

I still don't understand the observables, it would be good if someone could explain with real cases how to apply them....

[@Asaloy]

I really like the sketches but there is also a little bit too much information in a very short time.

[@dylanhall5305]

Thanks for not using marbles

[@_grzehotnik]

useless tutorial if you don't show any code to present your examples as
