[@Stakkeroid]

Found this clip via Stack Overflow and wow I finally understand Yield clearly and intuitively. What a great video, thank you!

[@challica]

This is why I love programing - if you are struggling with something, there are guys on you tube that will explain to you. Great video. Great community. One love.

[@madjayhawk]

You are master teacher. Very very clear. Thank you for taking the time to fully explain this concept.

[@katerahul2011]

The moment I see the yellow screen in the youtube thumbnail, I watch that video without fail because I know its going to be well worth it.. You are doing an awesome job.. Keep it up

[@siddharthshinde4480]

You cover in your tutorials very uncommon things which is the best thing about your tutorials !! Its difficult to find explanations on these topics at one place. Thank you so much !!

[@knitinr]

The example on providing a running total is a good example of the yield keyword - it demonstrates the concept of stateful iteration perfectly!

[@KenzoArts]

Your explanations for "yield " keyword are more clear than the ones i saw on stack-overflow. Thanks dude.

[@dengelkemier]

Thank you! I was looking for a C# example that explained yield without a lot of extra noise. I found several, but this example was the one where I finally got it! Awesome!

[@DanAshurst]

Brilliant video, make this neat little feature of C# very easy to understand. Props for explaining the internals too!

[@carlosnavarrete1094]

Excelent explanation. Very concise and informative.

[@phongchau1013]

You're awesome. This is one of the few concepts in c# where I always had trouble with. Not any longer with this tutorial. Thank you. Btw, with out should be without, one word.

[@Theorchero]

9 years later and this really helped me understand. Thanks man, found you via Stack overflow.

[@venkir1408]

I always confused with yield and avoid using it. now I got it and will be using it. thanks for great explanation. gentlemen thanks for understanding that English is a foreign language for us and not mother tongue.

[@TruptiSatardekar0607]

Reading articles didn't help! However your video, diagram and debugging the code really made a difference. Thank you!! :)

[@Noxient8816]

Visualizing the static void main did it for me. Thank you for taking the time to post this for us.

[@nabilyousfi9557]

Thank you very much for taking the time to explain this.

[@spawankumar]

Nicely explained. Rather than going through many sites which do not even mention on what is discussed in the video we can watch the video and save our time. Thanks!

[@norfsk]

Thank you for these clear and concise explanations.

[@BashaBill5]

I was trying to understand yield today at work. This video helped me out. thanks.

[@suisgrand6752]

Thank you soo much for explaining yield in such clear way! well done:)

[@markrobinson5420]

Perfect example of a clear and concise tutorial. Excellent.

[@jjrock9916]

Clear, simple and straight explanation. Thanks a lot

[@TheOceanLoader]

Great video.15 years and today I finally bothered to look up the yield keyword. Happy days!!! It was easy enough to follow. The only constructive feedback, if I may, would be to help you develop would be that if you ever intent to work in an English speaking country, it is hard to understand. Why does the Indian accent omit the "yee" from the beginning of "yield"? Also - the using the singular for "iteration" when you mean the plural "iterations". It's only minor but I thought worth mentioning because you're clearly a professional.

[@armanx2]

Best Explanation on yield keyword, for many many years i had issue to understand this thing.

[@THEspindoctor84]

you should be a professional teacher, this video is extremely clear and helpful! I hope you've made some money from this video. I also found it from a stack overflow post. Final note: it's early 2024 for me right now.

[@Arthur-cx1cg]

I dint understand a word, coz I dont speak french, but every your move.next() clearly described the intention of change with a great finale at async/await . Amazing knowledge. Will try to step through this in JS and then will do for C#. Thank you!

[@kannanparamasivam6453]

Excellent and clear explanation of yield...!!! Thank you very much for your effort.

[@SergeiKjtydghk]

Awesome example, thank you very much for so nice explanation!!! Have a good day!

[@ghostbusterz]

Great video, thanks for the clear explanation.

[@Thomas..Anderson]

Although I very much dislike videos where some programming practice is presented as they are waste of time, hard to follow and very little information is actually given. But, this one is a rare and blistering exception. Great tutorial. Appreciate the effort with additional animation. Thumb up. Sorry I have only one.

[@fthomm]

Thank you for your amazing way to explain how to use this. Great!

[@JibinMN]

Simply explained I watched some other popular videos about this topic, but none of them are good to me. But this one did the job Now i know the concept of yield and where to use and how to use THANK YOU

[@yussufsabih8215]

Great explanation , thanks

[@gyanprakashsa]

now i have clear understanding!! thnks

[@harrysanders818]

Awesome, now I got some light into that concept. Thank you.

[@javabgh]

This is an awesome explanation for yield keyword !!

[@ajinkyasagane8783]

Great explanation without wasting time covering main theory and practical

[@arielspalter7425]

Fantastic tutorial! You are talented teacher.

[@msayed84]

thanks from Egypt this was very helpful

Very clear and helpful explanation. Thanks a lot!

[@FunnyVideos-ni4iu]

Thanks a lot! masterfully explained, cheers!

[@StreamBits]

wow beautifully explained . great examples

[@ishan9815]

Sir, with due respect your explanation about preserving the data is a little confusing. If we observe the debugging closely, what 'yield' keyword does here is: When we reach the yield keyword in the for-loop, it returns to the caller BUT DOESN'T EXISTS the method and when another iteration comes, the execution resumes to the very next line of the yield return statement, which here is the end curly brace of the loop, so then it again iterates but from the same iteration count as you said in the video earlier, like it is resuming the execution of this method. So the running total variable never gets destroys but gets out of scope for a short period of time and as the execution of the loop resumes, it comes back in the scope with its existing value. Great Video sir, now it makes sense to me how CoRoutines work in Unity. Thank you

[@TheXunty]

@Shivprasad Koirala Sir, Why create another Filter method for getting values greater than 3 ? We can do this simply inside Main Method also.. ? Before printing the values to the console, just check whether it is greater than 3 or not... then what is the benefit of using Yield here ?

[@fahmifarhat7076]

Thanks a lot. Your explanation is very clear.

[@SomeRandomDude2007]

Awsome video.. Its a nice thing to know.

[@bhoopendrasharma9474]

Thank you Sir for such a superb explanation...

[@VaclavElias]

Thanks, finally I am understanding yield! :)

[@K6TJO]

Preposterous that there are 74 down votes to this video. This is a very clear video and has helped me comprehend this concept like no other resource I have found.

[@stephenl7998]

clearly explained. thanks

[@ahlamh8070]

Thank you sir, this really clarified my confusion.

[@MegaMage79]

this tutorials are AWESOME !

[@ravimakwana389]

Thanks, I had some trouble fully understanding the concept before!

[@atul121984]

Mind blowing....great effort..Thanks...

[@RockoShaw]

Excelent explanation, thank you!

[@akhilnegi100]

thanks for clear video...helped a lot

[@juanclopgar97]

I've a question, you can use the statment yield only when you return an IEnumerable or IEnumerable collection?, and this only works when you use an iterator (foreach)?

[@MaryamAv]

one of the best teacher i have ever seen in my life , thank you so much

[@rahuljagtap1249]

thanks

[@buddhikagunasekera5348]

Thanks. very clear explanation.

[@minastaros]

It even works when the generator function walks over deeply nested data structures, using recursion, thus, calling itself in potentially several levels and probably foreach-loops. And the receiver just gets one value after the other neatly serialized... That's not _easily_ possible without pre-buffering the results in next_element()-like functions.

[@sampathcse16]

Nice explanation. Thank you!

[@sac13p]

Awesome explanation with example. Read MSDN 2-3 times but not getting it correctly. thanks.

[@laksithliyanage2416]

Excellent Explanation!

[@patelmahesh80]

[@ibrahimfikry6624]

❤thanks for this valuable content

[@mushfigagayev4396]

You are really Master! Thank You.

[@KevTheImpaler]

Thank you for taking the trouble to explain to explain this feature.

[@stefanme668]

Yield return is a way of returning the value to the enumerator do do whatever it wants to do with it, without aborting the current block's execution. If you notice, the enumerator method does not start from beginning but "continues" where it left off

[@sultansallaj680]

Excellent video! Thanks!

[@v4raziel]

thank you very much....very simple way to understand...thanksss :)

[@s7887177]

Great video. I just forward this on instead of explaining myself now ;)

[@learnstuffz3002]

Thanks, I understand now what is yield

[@PramodSingh-kc1ne]

very good explaination.

[@DheerajPalagiri]

I dont understand how the method allows with out proper return type. You used innumerable as return type but not returning that. ..may be yeild does the trick. ..need some more research on yeild...

[@MikeStock88]

Great explanation

[@AndrewSteitz]

Excellent explanation! Your pronunciation of the word "yield" made it difficult for me to follow at first but I caught on. Thanks!

[@chezchezchezchez]

Andrew Steitz EELed. Simple.

[@ap4ever]

Provided great understanding about the yield keyword, but I have a question that is there any way where we can use it without foreach loop in caller function? Please Answer

[@TheRayglo]

Very clear! Thank you :)

[@vinodpasi8021]

Thanks Shiv...

[@RohitGTA]

Amazing explained
