I love how laid back your teaching style is. Great work! My success as an engineer is purely through the gracious people of RUclips spreading knowledge. Thank you!
Only discovered this channel the other day, now recommending it to anyone that has any interest in JavaScript. Loving your content and enthusiasm is always infectious.
You are simply awesome man!!! I am really enjoying stuff from you, making 'complex' concepts pretty simple. Please keep making more videos!!! Thank you
Having a great teacher is such a blessing. I'd never be where I am if it wasn't for the amazing teachers like Colt Steele, Maximilian Schwarzmüller and you.
Honestly one of the first tutorial series that shows an enthusiastic teacher as well as an entertaining humor. Both works wonderfully with each other for this channel! Keep up the great editing and content!
So fun that my node.js version read this right off the bat. No problem. "If you're watching this video from the future you don't have to do this". Learning a great deal through these videos.
Everything about the presentation style is engaging. Many people will benefit from how patiently you break down this topic. The other thing about functional style is that you don't necessarily have to decode what the loop is doing, since the loop merely tells you how to do something, but not what you were doing. Sure you can comment, but comments go stale and some people are terrible at updating them. The code is the truth. Once you learn some basic functional style and the standard functional transformations, you think in terms of map, filter, and so on... so you see what the program is doing, and you don't really worry about how.
Thank you! I was just about to ask in the comments. I'm pretty sure you're right too I just wanted to make sure. Well, suppose we could write the code and run it too to test but I'm lazy. :)
Thank you so much for filling this void. You are tackling issues that many in the learnjavascript community see as a the first large jump in difficulty!
Joey Leung Thank you so much for saying that. It's exactly what I was going for. I'm a firm believer that functional programming isn't harder to understand than object-oriented programming - it's just badly explained.
Hear loud sipping sound; instantly parched. Also -- Thank you Thank you Thank you!! Can't say it enough. I find reading about this stuff very dry and confusing. You've helped me immensely and your passion is contagious.
been subbed(on my main acc) for so long, i was stuck on an excersice (googling for 20mins) then randomly searched here, saw your video and got the answer in less than 2 mins, thanks!
great stuff. just used filter for the first time yesterday, and stumbled on your videos today. very well organized, and easy to understand. Keep it up. Functional programming === the best way to program.
This is awesome! Your personality complements with your teaching perfectly. It is educating and entertaining, much better than reading more javascript books. There aren't much material out there that really go into detail with higher order functioning other than eloquent javascript but the examples there are difficult to parse.
You can add the fact that log may be used as an higher order function to compose all the things : console.log( animals.map( a => a.name ) ); **classy** because this function is an expression !
Thank you for making these videos!!!!!! You truly have a gift for communicating potentially tricky concepts with such clarity. I will continue to use your videos throughout my coding journey (which began in December 2016). Thanks again!
Thank you for your videos! I have been struggling to learn very basic concepts. Your videos have helped in ways that looking at online Documentation alone just has not. Thank you!!
mpjme hey man! I absolutely love the way you lay out the material and THEN break it down into small peaces that are easy to be understood by mere mortals like us, I've watched well over 20+ high order function videos and none of them made sense anywhere close to the way you make sense, I'm really glad I found you, finally somebody speaks the language I do :) I hope you gonna continue with making these amazing videos, thanks whole a lot for doing this, peace
This makes me VERY happy to hear, this is exactly what I'm going for. As for "speaking language the way you do", I think it's just good language. To be perfectly honest, this is all just public speaking 101. Anyone who has studied basic rhetoric and writing will do what I do - the problem is that it is very rare for techies to be interested in humanistic subjects too, so that is why it is hard to find material that is presented by someone with proper training in presentation. I think a lot of people unnecessarily feel stupid because programmers lack solid communication skills. As a field, we really need to shift our focus a little bit from writing code and thinking a bit more about communicating about it. Getting more women into the field would be a good start.
Just have to say that I have been learning so much from your videos and they are always entertaining so I don't loose concentration. Love your work! Please keep them coming. 😁
before to understand better arrow function ( and the same for coffeescript i would say) a very good javascript understanding is necessary i think, congratulations for your channel, top quality stuff, keep up the good work
hey there ,,,, watching this from the future ,,, it was recommended by fullstackopen course by University of Helsinki amazing video btw,,, it made understanding higher order functions so much easier thank you ❤❤❤
Great way of explaining and teaching, ive learned more in a week of waching you that two months of random tutorials, suscribed man., and keep the great work.
Thanks so much for making these videos! Now that I'm past the absolute basics of learning JS, it's really hard to find informative/helpful content on the more intermediate/advanced concepts. I'd love to see a video series on React.js using ES6!
I really like your style in explaining the point, please let me know if you are organizing any meetups at Stockholm as I would be interested to attend. Thanks !
Really great set of videos! You can make it a little more concise: var names = animals.map(x => x.name) you had: var names = animals.map((x) => x.name) Parenthesis are optional when there is only one parameter.
when you receive only 1 argument in the arrow function, you can also leave parenthesis out. var names = animals.map(x => x.name) and make it even shorter. I don't think that renaming a variable to a single letter is a good idea, it makes the program cryptic, I prefer to keep it more readable even if that means longer code. I also think that shorter code doesn't mean less bugs, I think that simpler code means less bugs, yes simpler code is shorter because it has less stuff (less parts is simpler) so this means that a correlation between shorter and less bugs exist but correlation is not the same as causality. This difference matters because when you try to shorten code just for the sake of shortening you risk creating cryptic code that can result in more bugs instead of less.
+jorge rivera please note that were not simply talking shorter code here. I probably should have left out the arrow functions from these examples because it confuses my message. The code is not short because we are writing with a more terse syntax, it's that map genuinely saves us from writing logic. I talk about this in part 1 of this series I think, this video is part 2.
funfunfunction I have watched the whole series, very good material I'm now a subscriber to your channel. In the previous comment I just wanted to make it clear for everyone watching the video that shorter is not what make it better, simpler is. Because I think that the way that it was stated may lead to the wrong assumption. I know how difficult making this kind of tutorials is because I have tried to make some videos myself but I didn't uploaded any because I'm not satisfied with the end result and you are doing such a great job in this channel and I just wanted to say thanks
Can you do a series on computer science fundamentals and javascript please. These are great vids on basic functional programming in JS, but I think it would be cool if you talked about CS concepts too.
Thank you for sharing your knowledge. Great work! It would be stupendous if you make a bunch of episodes on frontend architecture using vanilla JS. Maybe you could also share the 20% of patterns set you use on day to day basis.
This is the first time a tutorial genuinely made me laugh :D (@ 1:08) The videos are really fun to watch and full of life. Needless to say, concepts are explained very well too.
in c# we have this since 2008 :) and great library which is called Linq(Language Integrated Query). I've found some JS library which is called LinqJS. that was amazing :) Arrow functions are called Lambda Expressions in C#. great tutorial thanx :)
Also, in arrow functions, if you have a single argument, you can remove the brackets around it. So you basically would have: const names = animals.map(x => x.name);
Awesome videos!!! Just to mention one thing- you dont need parenthesis if you have only one parameter on arrow functions: var names = animals.map(x => x.name);
You can lose another two characters if you get rid of the parenthesis around 'x'. Good video by the way, love the one you teach currying, really blew my mind!

i'm a student in design school and this is helping me wrap my head around functions a lot better omg thank you
when there is a single parameter the arrow functions does not need the ().. so it can be x => x.name i thin, instead of (x) => { return x.name }
Thank you! I was just about to ask in the comments. I'm pretty sure you're right too I just wanted to make sure. Well, suppose we could write the code and run it too to test but I'm lazy. :)
This is true, and leads to even cleaner code! Woohoo!
I almost felt like removing the extra () in his editor 😂
You are absolutely right but all JS Linters recommend to use parentheses
These videos are incredibly helpful. You have a real talent for clear and engaging instruction. Much appreciated!
