My only wish is that this video was 35 minutes long with 20+ examples instead. So great!! Thanks a ton!!

As a fellow game developer, I humbly suggest your tutorials to my team, especially the simplicity and real world samples are just on point. Keep up the good work and thank you for sharing👍

This tutorial was perfect, I really like how you compared lambdas to a more simplistic loop. It helped it click in my head

There's also the thing about performance. Althought in many case LINQ is fasterish and less bug prone than manual foreach ( things like .Except() and especially parallel aggregation), most of the time LINQ will be slower, because of the overhead of delegate invocation. And not even speaking about for loop which is way faster then foreach. So if you actually need to care about performance for example rendering, real time data analysis, etc. it's good to be aware and benchamarking of test subset won't ever harm you.

That Cyberpunk joke cracked me xD

You break things down and explain it really well. Also your voice is clear, calm and not rushed. And no stupid drawn-out intros. Thanks for posting - will watch more of your tutorials.

This is extremly helpful. I've known a bit about lambda functions before but making one actually blew my head off.

THANK YOU SO MUCH. I've been looking everywhere for a tutorial which really deconstructed lambda expressions, but couldn't find one anywhere. You are a lifesaver.

You could honestly teach teachers how to teach. You're that good.

While i agree that lambda's are awesome, what you're mostly focusing on here is LINQ, and NOT LAMBDA's (though you are using lambda's with linq, which isnt not really required). The select/where/orderby/etc are all LINQ functions. The "n => n>5" is the lambda part. Everything else is LINQ. Lambda's have FAAAAR more uses than just LINQ. And LINQ can be used without lambda's.

I have struggled with lambdas A LOT (I think mainly because most examples of it that I had seen were so abstract and high level), but this has been probably the best explanation of them yet. Thanks!

This actually was so simple but helped so much, I hope you can do a “C# tutorial series” or something along that line! Keep up the good work man

The world of lambda expressions seemed so harsh and difficult, until I saw your video. Thanks for the simplicity 🙏

Love the threatening aura intro then complete coddling immediately after 🤣 needs to be in more vids

there is a downside to using LINQ lambdas instead of for each and that is you can't step through the code that is being iterated upon, so while it may be simpler to write, you are actually making the code much harder to debug. This is fine if the code is simple and will not throw any exceptions but as soon as the code becomes complex and is likely to throw exceptions while iterating through the list then you'll have a really hard time debugging it.. An example of this is using LINQ to initialize a list of objects from a set of records that come from a database. Lets say there is a conversion error when attempting to convert one of the values from the DB into the datatype of the object property you are trying to set. Using LINQ you have no easy way of knowing which item in the list failed. So yeah lambas are great until there is a problem that can only be debugged by stepping through code.

Just to add to all comments above, your typing speed is outstanding😳

Jacked and C# instructor? I am among my peeps! Thank you for your precious help!!

I enjoy your videos. Though I've been using and making lambda functions for some time, seeing them this way taught me something new.

I like this video because you encourage people to look into other options. :) Keep up the good work!

The cyberpunk joke won me over. Good job.

Hey man, i have to say it, your explanation was crystal clear. It was as relaxing (no noisy music and what's up boyz) as it was helpful. Thank you.

Great video! Really glad to see tutorials that cover more advanced topics for beginners. I do find this tutorial covers a lot of System.Linq, which might cause beginners to mix that up with lambda expressions. Lambda expressions is simply a short hand to create an anonymous function. I think it might be beneficial to cover the following: - Differences between anonymous functions and Linq/Extension methods. - Other usage of anonymous functions (i.e. assigning a function to a variable/parameters, callback using System.Action)

I have never understood lambda functions before and you just made it so easy. Thank you so much for this video, even if I do feel a bit sick at all the time I wasted writing loops that I didn't have to write.

KZfaq has been recommending this video for literally half a week. I should have watched this sooner lol. Great video!

You are a great Teacher. Thank you

the intro has this vibe i cannot explain....

Man this was great just explained two advanced topics in 6 mins

Wonderful! So easy to understand!

very clear and easy to understand!!

Thank you very much. It's really helped me!!

Wow, C# is really great, thanks for these infos

Thank you very much ! Very useful video !

You sir, are a legend. Thank you for this.

the best tutorial i've ever seen

👏👏👏Excellent explanation. Clear and to the point.

Great video. Always good to refresh your knowledge or learn new stuff

Thanks very much for this, subscribed long ago 🎉

Man, you never disappoint, thanks!

I'm in love with c# wow

That burn on cyber punk though. God damn! Very informative. I know how to use lamda but not really why it worked that way. Even picked up some new uses. Thank you for a great video!

I don't think that Cyberpunk reference will ever get old, even if Unity updates their code 10 years from now :D

Love the golden ratio used in the list example

Great Tutorial Thanks m8

Just purely amazing!!

thanks fam! great video!

This is amazing, thank you so much!!

Dude you really have a special gift in teaching complicated topics... There's really no better way of breaking down this topic... Thanks for your good work!

Those have a C# background before moving to Unity like me are already using it extensively. During the course I have read on some blogs and Q&A forums that Unity might have performance difficulty while processing these expression. Some even said Foreach loops are bad. But so far I haven't observed any issues. Go for it, you can reduce your code by 30% and less time on maintenance.

Nice tutorial, and bonus points for including Valheim in the list of Steam games (one of my all time favorites). 😀

That was rad dude!

This stuff was so much fun to play with. Proceeded to write the dumbest code to make a string basically nonsensical and I couldn't be more proud of my work.

I just feel calm looking at these tutorials and even on the way I'm getting smarter and developing my code knowledge

make more of these you're an exam saviour....

love your sense of humor

If only this video would last for an hour showing examples. Amazing stuff

Whoa. Solid video

Great explanation

This was really helpful, great tutorial!

very good thank you my friend

Awesome!

Your videos are AWESOME! You are very didactic, patient and interesting, thank you so much! I've been trying to learn pure C# but whenever I ask questions to a "friend" of mine, he mocks me, says I should have known that already, that my code looks like shit.... You, on the other side, make the learning process productive and healthy. Thank you so much!

Been using linq for a while now. Love the lazy processing and REAL composition, not just employing a tool for composition, which is what the ':' really is for c#. there are more rules you have to follow for real composition, but it gives you so much. Which is one of the fundamental reasons why linq is AMAZEBALLZ. I would not be surprised in the least if the first intelligent aliens we meet have something startlingly like linq on the IL level. It is kind of close to a pure logical expression of the act of parsing related data. Maybe we should be pumping low level linq code into space, prove that there's at least some intelligent life stuck to this rock.

Thing I didn't know I needed to know

OMG I FINALLY GET IT. THANK YOU. lol

best unity tutorial!

underrated!

bro is teaching and doing asmr at the same time

"Cyberpunk destroyed our condition, just like it destroyed our dreams" - Tarodev

Gracias Mister Tarodev que poder de las expresiones Lambda.....saludos de los andes peruanos

Awesome! Thanks for your content! Not sure if someone already mentioned this before, but as soon as you use foreach in a lazy IEnumerable it will force the query execution. Not sure if that was the intention in your AddRatingToNames method. If you want to stay lazy you could do this instead of using the foreach: return games.Select(g => { g.Name = ...; return g; });

Good video

Damn good bro

Subbed.. lovely

Great ☺

damn, this is called lamda? so I did it on accident every time. Learned this on tutorials and didn't knew the other way thx for this :D

"just like it destroyed our hopes and dreams..." - genius.

This is more like a System.Linq tutorial than general lambda expressions. But anyways this is still good content.

Big Like ( within start of a min ) watching this video

I feel for you bro. I know that mood.

compact tutorial!

Always give variables descriptive names because it's not just going to be you reading it. Other than that great video thank you!

Unexpected bonus for Extension methods at 05:39 !

2:40 yup, that's a like and sub right there

More examples, nothing else!

It's all fine and dandy, but hard to debug, which is why we don't use these as often. But maybe you have some debug tips?

cyberpunk burn lol, hilarious hahaha :)

Hi could you explain unity physics with examples ? Thanks great content btw

Question: If there is a list of items separated by two categories (owned and not owned by the player), should I use forloop or lambda? My thought is, if I use lambda, I'll have to do it t twice, thus I presume it loops through the collection twice, whereas running the loop just goes through once to separate the list. Your thoughts?

Nice video! Can you share your thoughts on using LINQ in Unity? Anything we should keep in mind?

Hey, what if I wanted it to be based on luckPercentage? I have a dictionary of items, each item has a float luckPercentage Item 1 = 10.0 Item 2 = 40.0 Item 3 = 50.0 So if I would want to take 1 item, item 2 and 3 would be the most often picked, and item 1 would be very rare. How can I achieve something like this?

can i change the value of the list using lambda ? like find the game named factorio, set its steam score to 9, using lambda, without creating a new list.

belleza!

Hmm .. It's more of a tutorial on Linq, isn't it? But clear and useful!

Really nice tutorial. The only thing I disliked is that you used var so often. To understand the connections a little better the specific datatypes would have been better for me.

oh boy 2:40 hit way to hard. great vid

you can use predicates lamda? right.

What am I missing??? When I do the same code you do I get an error. CS0246 C# The type or namespace name 'Game' could not be found (are you missing a using directive or an assembly reference?)

I not only use lambda's I use them all of the time with Joins and GroupJoins good times

I'm curious what is the lambda I know it's I Greek letter λ but what is the lambda you talking on the video ? So basically lambda is the (>=) faction? If that the lambda faction it's something I use all the time with out even knowing the name of it

Huh, I don’t know why I’ve never thought to make extension methods for an IEnumerable to basically make my own LINQ functions. Cool idea.
