[@mateonavarrette4864]

Great rundown! I never really solidified my DOM traversal skills in my coding bootcamp, we just touched on a bit of vanilla js then jumped into react. Thanks for clearing some of my confusion up

[@xenialxerous2441]

Hi!! I just wanted to say, that your channel and your videos are true to their perfection. As the name goes so as the content 🤗 Love you bro, your efforts are forever appreciated!!

[@cacup7]

The best traversal class. You rock on teaching and you are proving for each video that you are simplifying the web for everybody. Congratulations, man

[@tdematos]

One of the best videos that I have seen for traversing the DOM. It's extremely easy to understand to the point, and very clear on what each action does!

[@neelamchaubey28]

Thanks so much for explaining the most powerful DOM Traversal methods in such an easy way, Kyle! Keep up the good work👍

[@devt.9712]

Dude you are amazing.Thanks for making that Frontend/Backend guide, it's so easy to follow and makes my learning process a lot easier. Love you!

[@ThiagoVieira91]

Had to deal with these this week. This video would help a lot. Thank you Kyle! 👍🏼

[@alinademi]

It really did simplify the most important parts of the DOM traversal. Awesome job!

[@mustafeezahmed9536]

Hey Kyle, your videos literally blown my mind. So much knowledge with so ease. Thanks a Lot buddy!

[@roey6541]

Such a pleasure watching you explain! These concepts can be tough but you're very assuring and confident. I rightaway went to check out your js course, and purchased it immediately. Looking forward on starting! Feels like the first day of school :)

[@WebDevSimplified]

Thank you so much for the support!

[@pabhay235]

too good with very simple examples. it cleared my concepts in 14 minutes sharp.... much appreciated

[@Dameworth]

You’re a natural teacher, thanks for all the videos!

[@NecquiTeja]

Thank you... appreciate your efforts in making these videos. Keep it up my friend.

[@mznunaya]

I JUST got done telling my bootcamp instructor how I need to review the DOM. And then I open my phone and see a notification for this video. Got dammit Kyle you've done it again. 👏

[@Guii0]

You're very good at explained things, it show us that it's not as difficult as we thought, actually it's really simple.

[@human3015]

These explanations are so clean, congrats on that!

[@coolcha]

Very good video and I appreciate the timestamps as I knew some but I could skip to those which were new to me.

[@lingtravis6325]

The tutorial is super useful and easy to understand. And it solve the problem that bothered me for 2 days . Thank you so much

[@francisugorji5639]

Thank you for simplifying JavaScript. I always learn new stuffs when I watch your videos

[@user-zd8nu5sl2j]

just start learning web dep, absolutely love all your videos, thank you for making and sharing those ❤

[@makiaboabida]

This is amazing man. Thank you for making this video!

[@jomesias]

Cool tutorial! This is exactly what moustache binding replaces, so no more direct DOM calls (of course react ref can always be used for specific scenarios ). Though dom tree navigation is still needed for certain applications, js frameworks are phasing this out. For better or worse👍👍👍 Btw THAT IS A KILLER LOOKING JACKSON GUITAR IN THE BACK! Loving it 🎸 🎸 rock on. 0:01

[@IELTSMANTRA-wy1rl]

You are literally the best teacher with clear explanations .. totally awesome content .. thank u so so much ..

[@TheCodingOdyssey]

This was interesting to me. I am a self-taught developer, but mostly worked pretty extensively with React in my job so not much vanilla javascript dom manipulation which I am looking to learn more.

[@pkorneev5226]

super super useful. Noone actualy talk much about dom traversal, but this is the most important thing when you learning JS. I had soooo much problems with that cos i know some programming in other languages and have ideas how to do smth in js, but i cannot simply connect my code to my html+css page, now it looks super easy.

[@AlThePal78]

I am so glad I am in your discord. Someone just saved my life lol or helped me with this. I also love your CSS Battles. You should do that with JS to see how you both differ in your writing functions, that would be awesome to see.

[@SocksWithSandals]

This is great for jQuery dinosaurs like myself who are moving to ES6.

[@souvikkundu]

Yep, almost same methods or notation

[@guchierrez]

great guide, literally the best material online for learning DOM

[@HolisticPython]

Thanks for all the free tutorials. Wondering if you could do a video on just general coding fatigue and any tips on how to remedy it?

[@naveen7513]

I am following your front end development road map as the stepping stone for my career bro. Seriously they way u explain is great and i think by following ur tutorial i can be placed in MNC or other web development firm sooner. But few things I can’t understand quickly it doesn’t mean ur teachings are not good it’s just me who is slow at the moment. But i am trying to push my limit to the end to grab the knowledge of how programming works. Thanks man!❣️🙏🏻

[@dipbhowmik5076]

I just want to say Thanks man :) from the bottom of my heart.

[@Ayomikun]

I just realised that I've learnt soo much JavaScript / React from you, it's ridiculous. Thank you!

[@nabilhaouam8497]

Why do you think it’s ridiculous ?

[@ntnurobert218]

Great ! I learned “closest”. Thank you

[@natalisulcer974]

Thank you so much !!!! One of the best videos!!!!

[@LanguageSkillz]

9:09 makes me have to clarify traversing along parent children across parent siblings. It comes up a lot with some layouts. Kudos with distinguishing closest for ancestors, and I appreciate how you go about familiarizing usage of techniques like detailing .children properties on a variable and converting with Array.from to establish an array simple to handle with .forEach. Built-in properties of ES6.

[@sacrajah]

Thank you , Kyle . I learnt something today.

[@webartem]

I like the way you explain it so much! even gonna forgive you missed semicolons and different quotation marks

[@espiritualidadedesvendada]

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

[@digigoliath]

Awesome!! Well explained & easy to follow!

[@shahidshafi1227]

You Just made DOM easy for me ❤️. Thanks a lot .

[@ohhellothere1111]

Havent used query selectors on anything other than document and first time seeing closest() method aswell. Good vid thanks dude :)

[@bentoth4324]

closest() is crucial, especially when dealing with events. (almost) never go up with a while loop

[@russellabraham9208]

Happy to see this video. I think you could have mentioned a few more details for a more rounded look at scope with querySelector. Also you can traverse in a chain with closest().querySelector().closest().querySelector().closest().

[@skaywalker20]

Very helpful stuff, thank you so much!

[@MbahmukongDestiny-up3tv]

Your methods are fascinating thanks alot🎉

[@karthikhs2530]

beautiful way of explanation

[@Rohan-bg8ci]

Thanks for revision!!!

[@pedrohenriqueduartebueno6873]

Your explanation is pretty good, 👍🏻👍🏻👍🏻

[@_Jordo]

I thought I knew all this but watched just in case. You taught me that closest goes upward. Thanks! PS. I am curious to see how you look without your hair styled haha

[@skylerjknight]

Nice simple tutorial. Thanks.

[@chickendev5759]

concise and easy to understand

[@thelostvorg7805]

I checked the Timestamps and I was like meh I know all of these but I watched the video anyway because you never know what you will find and then you mentiond the closest() function which I never knew existed ! I'm glad I stayed till the end of the video!

[@AcheiversOfficial]

very helpful. May the force be with you. 👍.

[@Adam-iq6zn]

I work as Front-end Dev for 2 years now (small and medium software companies), and I didn't know about closest, nextElementSibling and previousElementSibling methods at all 😲 Usually I write my own functions to find specific parent or sibling. Thanks for enlighten me about this xD

[@focusme-tv3650]

Hi ! Just wanted to check if I knew everything about traversing, so classic check up. I do, but god your video was just extremly clear and pleasant to listen to. I subscribed ! =D By the way, for the beginners, the main difference between "parentElement" and "parentNode" methods is that the first one returns an HTML collection, which is kind of an array storing ONLY elements, while the second returns a nodeList, which returns all the parent nodes. Nodes can contain elements but also text / comment etc. ... So it's not a weird behavior but more a very specific method that we, as web developers, need to take in consideration.

[@dhawalparmar7117]

Bro it is best youtube channel for javascript tips and tricks....Please make tutorial on angular react and vue

Great video ive been struggling so much with this concept as ive been using the odin project and in their js course they keep linking to articles that provide examples for all the basics of js but they use these damn selectors and DOM manipulation in their examples which has made learning js 100x harder than its needed to be so this video is a huge help

[@toluwanimiayodele1858]

Brooo, I’m in the same situation, I love the Odin project but Mann these damn dom manipulation. How is it going now for you?

[@stevenleonmusic]

One thing you can't easily do with Vanilla JS even in 2021 is search for siblings that match a selector. I use this on our website because we have togglers that affect sibling elements below them on the page and sometimes they have descriptions in between or images so we can't reasonably just use nextElementSibling since it may not be the very next one. You can do this easily with recursion. If you need full up/down capabilities: const findSibling = (element, selector, direction) => { if(!element) return null; direction = direction || "down"; let methods = { up: "previous", down: "next" }; let next = element[`${methods[direction]}ElementSibling`]; if (next?.matches?.(selector)) return next; return findSibling(next, selector); }; If you just want to search down the tree (and never up): const findNextSibling = (element, selector) => { if(!element) return null; let next = element.nextElementSibling; if (next?.matches?.(selector)) return next; return findSibling(next, selector); }; There's no real fear of infinite recursion since next/previous ElementSibling will eventually return null.
