Learn JavaScript DOM Traversal In 15 Minutes

[@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. 👏

[@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 ?

[@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

[@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!

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!!

[@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

[@randymartin9040]

Great video, Dom traversal has been pretty difficult for me to figure out, this helped a lot. Thank you

[@Gerry090]

For those who are on the fence about his JS course, I suggest you buy it. I'm following his course and I can tell you that Kyle is a great teacher!

[@ShinAkuma]

The only time I ever touch jQuery is when I need to traverse the DOM and now I don't need it at all. Thanks a lot.

[@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!

[@revizion9101]

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?

[@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.

[@SocksWithSandals]

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

[@souvikkundu]

Yep, almost same methods or notation

[@neelamchaubey28]

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

[@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

[@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.

[@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.

[@Dameworth]

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

[@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

[@pabhay235]

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

[@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!

[@IELTSMANTRA-wy1rl]

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

[@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.

[@francisugorji5639]

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

[@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

[@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!❣️🙏🏻

[@stefanmitrovic7680]

I only watch your videos about website programming.This only says how good you are at explaining code and most importantly is easy to understand and also to memorize. 🤗

9:50 is such a shocker I had no idea thanks yo!

[@amiraalabeedi541]

Thank you. Iv watched several videos of js and css in this channel. Very very useful.

[@guchierrez]

great guide, literally the best material online for learning DOM

[@giovannielias8153]

you could select the next child with document.querySelector("#child-one +") Remember that in a query selector you use CSS selectors, and with the new CSS stuff like :has, :is, :not And each CSS update, querySelector is more useful

[@啾啾啾-k2t]

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!

[@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().

[@ntnurobert218]

Great ! I learned “closest”. Thank you

[@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.

[@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.

[@Zachariah_Pini]

Subbed, watched full vid and clicked the bell icon. Thanks dude you are the G.O.A.T!

[@mark-y]

Nice video, but one mistake (9:31) - you can apply getElementById selector only for document element

[@WebDevSimplified]

Good catch!

[@StephenHind]

At multiple points in the video you use the children selector sometimes prefixing with Array.from and sometimes without: I'm guessing the Array.from isn't necessary as you directly access the children using forEach without Aaray.from?

[@sebastiansimon7557]

@@StephenHind No, there’s a difference between `HTMLCollection`s as returned by `getElementsByClassName` and `NodeList`s as returned by `querySelectorAll`: the latter has a `forEach` method, whereas the prior doesn’t.

[@shahidshafi1227]

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

[@arkemiffo]

It's amazing really. I've been a happy amateur in Javascript for many years. I'm by no means an expert, and you'd be hard-pressed to classify me as good, but still. I know my stuff. Every now and then though, something pops up that simply rocks my Javascript world. For years I've been mumbling select swearwords for having to build proper loops for looping element collections. And then you just go and point out something so ridiculously obvious it annoys me. Just make an effing array of them...

[@ThiagoVieira91]

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

[@pawejakubowski829]

[@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.

Note that closest() starts by checking itself, not its parent. This may (or may not) make a difference.

Thanks! 11:30 - I think that (by mistake, because it "appears" on the menu) - It is the first time that you mention the word "Node" in the DOM concept. What are the use/purpose/best practice for all of thsoe DOM manipulations with using those Nodes? It looks quite important... Do you have any video about this subject?
