Hello, I'm getting back into web development after a 20+ year absence, and it's pretty scary because everything is so different! Your channel has been a big help. Thank you so much for your clear explanations and tight presentation. Very valuable!
I watched a few videos of yours and was quickly convinced. I’m subscribed to your channel, your news letter, and checked out your “appearance” on the How to Code Well podcast. Really like your quick and to-the-point style of teaching, and you move quickly so I don’t get bored at all. I can always pause if I need to, but so many channels move too slowly. Thanks for all the help!
Thank you so much! I spend a lot of time trying to make sure my pace of explanation is a good mix of quick without being too fast. I generally live by the principle of explaining something really well once and then moving on since it is a video and not a live lecture you can always pause or rewind like you mentioned.
Steven Griffith is a very good TH-camr too, he has videos about almost anything you could think of in JavaScript, web dev simplified does help a lot, but sadly there few stuff he hasn't covered about JavaScript in his videos, and sometimes he simplifies things a lot, which is good if you are struggling to understand something, but some concepts is good to know a little deeper. I recommend watching web dev simplified as an introduction to a topic, and then searching the concept deeper by watching some other videos, like the videos Steven Griffith makes, except if the concept is already simple enough and doesn't have much else to learn, like the array methods we were taught in this video, there do are some stuff he didn't talk about, about reduce method for example I believe it also can take a third parameter, but this video pretty much covered everything about these array methods.
How is it that I read so many array methods articles and couldn't wrap my head around them, but when I watched this video everything made perfect sense? You're amazing, thank you for making these tutorials!
Very useful summary! But keep in mind that with the forEach method you don't have the option to skip an element or to break the loop, in those cases you still need the 'for' loop or the 'for...of' loop so you can use the 'continue' or 'break' keywords.
My word thank you for showing this with multiple-property objects. Everyone does it with zero-property objects. You sir earned a sub 26 seconds into this video.
Thanks man, i'm glad that every time im entering to TH-cam i see one new video of yours, made myself an habit to watch at least one a day to refresh my mind in some subjects that i might forgetting and sometime also get to know for the first time.
This video is one of the reasons that I preach people learning sth in this era wouldn't require taking particular courses and having high-paid pedagogues... THANKS SIR♥️♥️♥️♥️♥️♥️
Such a clear and concise explanation of the subject matter. Keep up this good work! This is my first go-to channel whenever I need a lesson or need to gain understanding on a particular subject, no doubt.
I watch your videos whenever I want to take a break from regular work and learn something new and interesting. All of these methods made perfect sense when you described them. I'm eager to play with a bunch of these now. Thank you so much for the clear and concise explanations! :)
This is (by far) the best explaination I've come across. I'm thinking that what probably makes array methods somewhat confusing in other explainations is that they usually introduce the concept of callbacks. It's much better to learn these ideas seperately. Before mentioning them as the array 'callback' methods.
I see a lot of possibilities with this methods, filtering menu or items in an e commerce store, adding up the total of a shopping cart, thanks for this, it is extremely useful
Thanks so much bro. I watch your videos a lot, mostly for entertainment and motivation but this helped me out a ton. Currently doing The Odin Project and this helped me understand array methods much better. Thanks for your content. Hope you beat Kevin P next time 😂
That is a very good tutorial. I found particularly interesting and well done the way the reduce method was explained, it was clearer than many other videos on the topic.
I have always wondered what performance gain there will be if instead of arr.every(... x < y) -- which will require going through the entire array to determine the case you use !arr.some(... x > y) -- will only need to find one that breaks the case - worst scenario is, the last entry is the breaker - best case the first is the breaker. Notice the negation for 'some' and the reversal of the operator < to > or > to
Love it, simples! Also I like that this guy doesn't use semi colons; Though I get caught out not using them sometimes; The benefits outway the risks; Ops; I subscribed :)

This is the most simple, short, good quality and well explained tutorial I have ever seen.
Thank you so much!
I wish more people made tutorials like you.
Clean , Short , Simple.
subscribed , hoping for great content in the future.
Thank you so much! I'm really glad you resonate so well with my teaching style.
All these dudes are getting a pay day when I land my first job soon
additionally no 5 minutes "please subscribe" introduction
Agreed
@@ThatGuyDownInThe Did you get the job ? where's the pay day waiting for it mate
I swear this guy explains things better than anyone else on the planet
Wow, the best 10 minutes used to learn how to deal with arrays, Thanks a lot :)
You're welcome!
I'm new to javascript and the guys at work were paying me out for using for loops. This was very helpful.
Check out lodash for similar tricks, although than one is a library
Please view my short funny vid on arrays th-cam.com/video/LEKx0L4ukhs/w-d-xo.html
Yeah, not a single second wasted !
5 years later, and still this is the best teacher on youtube! Thanks man, you're awesome!

20+years ago.. what we had was more like web design.. but i feel you bro.. welcome back🤗
No fluff, straight to the point! I really thank you for this video!
This tutorial has more knowledge than many 1hour+ tutorial videos. Well done!

Superb explanations. Wish your channel to grow, you deserve it.
Thank you! I already feel like I have grown so much.
Crisp video and right to the point!
Thank you. I'm glad you enjoyed it.

The reduce method has been confusing me for a little bit as a is newbie. The way you explained it made so much sense! Thank you so much.
I was just planning on creating a video about array methods! Nice one! :)
Nice! Hopefully it goes well.

It's probably incalculable how much time and mind power this video has saved me. I am so glad I came across it. Hero! Thank you :)

Can't believe I just learned about all these methods under a 10 min tutorial. Man love & respect for you. 🙇♂🙇♂
You are the best!
Concise, no bs, no nonsense.
Please don't change.
And please don't add any silly bs in parenthesis like (as this, or as that...)
Best video ever. Simple, easy to understand. Effective presentation. Looking forward to more videos.
Been binge watching your videos.
Thanks a ton..
I'm so glad you went in-depth with explaining reduce. I just started learning software dev 2 weeks ago and couldn't wrap my head around it.
Can't say how much I appreciate these videos. Straight-forward, simple, and most importantly, useful!
How is it that I read so many array methods articles and couldn't wrap my head around them, but when I watched this video everything made perfect sense? You're amazing, thank you for making these tutorials!
Dang, if I had had the smarts of typing my problem into TH-cam a couple hours earlier... you saved me dude! (just starting this JS journey)
Very useful summary!
But keep in mind that with the forEach method you don't have the option to skip an element or to break the loop, in those cases you still need the 'for' loop or the 'for...of' loop so you can use the 'continue' or 'break' keywords.
Couldn't you just use an early return
Funny how much more helpfully and clear this is about these methods over some tutorials that spend 30 to 45 on each method
My word thank you for showing this with multiple-property objects.
Everyone does it with zero-property objects.
You sir earned a sub 26 seconds into this video.
That may be a TH-cam record :P
I'm really glad you enjoyed the video.
Thanks man, i'm glad that every time im entering to TH-cam i see one new video of yours, made myself an habit to watch at least one a day to refresh my mind in some subjects that i might forgetting and sometime also get to know for the first time.
Every video you make is gold. Never unsubscribing
I don't why this video had 200 dislikes. This type of videos are rare in TH-cam . I like this video so much 👍👍👍👍👍👍👍👍
Simple, but yet so accurate, and easy to understand!!👌
This video will deliver the expectations you expect from the title. Simple and straightforward
For C# developers, who know LINQ:
filter == Where()
map == Select()
find == FirstOrDefault()
some == Any()
every == All()
reduce == Aggregate()
includes == Contains()
you're welcome.
it is includes not include
Name methods in js are much more natural
The C# names are much better!
i love that most of his videos are fast-forwarded it makes it a challenge to keep up sometimes XD
This video is one of the reasons that I preach people learning sth in this era wouldn't require taking particular courses and having high-paid pedagogues... THANKS SIR♥️♥️♥️♥️♥️♥️
Man this was just amazing. You explain it with such simplicity without complicating and confusing the viewer. Thanks man
This simplified so much of the confusion I had around these methods. Subbed!
Finally someone explained reduced() simply
Easily one of the best channels for js, thank you so much , subscribed!
I've just found your channel and you're a great teacher! Thank you for sharing your knowledge. Thanks to you, now things started to get clearer! :)
Excellent !!! Each of your videos is answering many of the questions that I have in such a short time !!!! Thx and keep it up !!!
Thank you. I am glad you enjoy my videos. Hopefully my future videos are just as helpful.
This is a really worth tutorial to watch for every newbie programmer. Finally started to understand the array methods. Thanks from Kyrgyzstan!
This is the best video I've seen on array methods!🤯
You helped me a lot, i was strungling with this array methods and i can't thank you enough
No bullshit, just pure explanation. Awesome!

This video is only 10 minutes, but explained commonly used array methods so well! Ty for the great tutorial💯
This is wholesome! Clean, Clear and Concise! Props
DUDE!!!!! you cleared up soooo much for me, thank you man
I'm glad I could help
awesome tutorials. it' s so nice to watch a tutorial where they don't have a bunch of small talk in all areas of the video. just no nonsense.

Your channel is one of my main go-tos for programming knowledge. Keep up the good work, my friend.
Efficient way of learning! Short, clear and easy to understand. Much appreciated. Keep up the good work.
I've been working with firebase using for each without understanding it completely. Thank you for your insight and contribution!
This man is doing such a great job , the way he explain things are great. Thank you for you contribution👏.
Thanks!
Thank you for the support!
Thx from Ukraine. You explain clearly, and even I understood
Hi from Belarus, and thank you very much for the video! It was important and helpful for me to freshen up all array methods in my mind.
This guys needs only 10 minutes to discuss this awesome topic but in school it will take 1 whole week.
When learning Javascript you start to learn 10 percent then.... 5 years later you finish with the last 20 percent of knowledge.. Good stuff mate
Simply the best tutorial on array methods
the most informative easy video on youtube about arrays
This video has made my day ! I learnt so much that I really wanted to have the exact explanation ! Thanks buddy.
Thanks so much bro. I watch your videos a lot, mostly for entertainment and motivation but this helped me out a ton. Currently doing The Odin Project and this helped me understand array methods much better. Thanks for your content. Hope you beat Kevin P next time 😂
the currentTotal is lil bit confusing but you explained it very good.. thanks dude.
Thank you so much, buddy. I was struggling with this until I stumbled onto your video. Thanks a lot.
I'm glad I could help!
the best teacher in the world. tnks for every thing
Awesome video Kyle. Your teaching style is great, thank you.
You're welcome!
After I watched only 2 of your videos, I subbed. Thanks for the great content and explanation!
Thank you best explanation I have seen thus far...keep up the good work !!!!!👍👍
Much better than other channels. Kudos!
Good, crisp, precise, and very understandable. Thank you so much. It was just what I needed.
Reduce is definitely my favourite Array method.
Bro this is too easy, thank you for making this tutorial I learnt soooo much in such little time)) 🎉
Beautful super awesome ... you are so clear, concise and to the point ... have come across many tutors but you explain it the best 👍
U can use reduce to consume an array of promises step by step
await [1, 2, 3, 4].reduce(async (prevPromise, nextValue) => {
await prevPromise;
return new Promise((resolve, reject) => {
setTimeout(() => {
console.log('nextValue', nextValue)
resolve()
}, 200)
})
}, Promise.resolve())
Wonderful video!!! Thanks for unlocking the JavaScript lost inside me!!!
I'm so glad I subscribed to your channel 😁 you've got a efficient way to explain things, thank you for the tutorials!
Seriously thank you. This helped me past a huge block I had developed. Such a simple solution. Thank you!
That is a very good tutorial. I found particularly interesting and well done the way the reduce method was explained, it was clearer than many other videos on the topic.
Gem of a video man. Thanks a really lot

great explanation of array methods in a simple, understandable way. Thank you!
Helped me pass part of the entry challenge to the coding bootcamp I'm going for - thank you !
Thank you web dev for such an easy explaination. I hate reading mdn so please make more of such videos. Kudos👍👍👍👍
Very short and clear to the point. 🙏🙏
Thanks man. One of the best tutorial I even seen. Please make videos on Js, Node, Vue, Express and making full stack projects with them. Thanks again!
I have a full stack Node.js series that covers all these topics except Vue.
Love it, simples!
Also I like that this guy doesn't use
semi colons;
Though I get caught out not using them sometimes;
The benefits outway the risks;

I subscribed :)
Beautifully done! Clear and concise as usual. Thank you!
So cool and easy to understand from your video man, keep going 👏👏🙌
Thanks! I'm glad you enjoyed it.
I was seriously thinking of the number 7 during your "includes" section :O
Woah. First time viewer. Super great! Very clear and informative.
Thank you so much! I'm glad you enjoyed the video.
So simple yet helpful, thank you!!
Straight forward, clean and clear, thanks a lot.
Dude this was the best video explanation for this possible. You make it simple. Thanks a lot just subbed 👍🏽
Thanks for explaining the reduce method in such an easy to understand way!
Omg man! The fiilter i didnt know about! This solved a hell lot of issues! Thanks!!
I'm glad I could help! The array methods are awesome.
Thought I was already subscribed...Glad I realized I wasnt and did the right thing. You are an absolutely excellent teacher
