    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 :)

    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

  • @Adam-iq6zn
    @Adam-iq6zn 4 ปีที่แล้ว +3

    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

    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!

    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.

    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

  • @stevenleonmusic
    @stevenleonmusic 3 ปีที่แล้ว +1

    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.

    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👍👍👍

    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

    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.

  • @LanguageSkillz
    @LanguageSkillz 3 ปีที่แล้ว

    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.

    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...

      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?
